How do you know the difference between a odd, even, and neither graph?

Answers

Answer 1

Answer: Even functions

Symmetric about the yy-axis

When you plug -x−x into the function, it will simplify to be the same as the original function. This means that it doesn’t matter whether you plug in xx or -x−x, your output will be the same. So

f(-x)=f(x)f(−x)=f(x)

Below are graphs that are even and symmetric about the yy-axis.

even functions are symmetric about the y-axis

Odd functions

Symmetric about the origin

When you plug -x−x into the function, it will simplify to be negative of the original function, or the original function multiplied by -1−1. This means that when you plug -x−x into the function, you’ll get the same output as you do when you plug in xx, except it will be negative (or have the opposite sign as the original output). So

f(-x)=-f(x)f(−x)=−f(x)

Below are graphs that are odd and symmetric about the origin. Be sure to visually compare quadrants that are diagonal from each other (quadrants 1 and 3, and quadrants 2 and 4).

odd functions are symmetric about the origin

Neither even nor odd

Not symmetric about the yy-axis, and not symmetric about the origin

The function has no symmetry. It’s possible that a graph could be symmetric to the xx-axis, but then it wouldn’t pass the Vertical Line Test and therefore wouldn’t be a function.

functions that are neither even nor odd

Final answer:

A practicable solution is one that complies with all limitations and specifications. When all of the requirements and constraints cannot be satisfied by any combination of decision variable values, a solution is deemed to be infeasible. The parabola's highest or lowest point represents the ideal value. If only the parabola expands down words, the optimal value, also known as the vertex of the parabola, would be maximal. The minimal value is one opening upwards. The vertex's "Y" coordinate is it.

An option for making a judgment or a resolution that does not adhere to one or more constraints. The corners of the entire model's graph would contain the ideal answer.

Step-by-step explanation:

We are looking for the number of students that rode in each bus, so first lets subtract out those that drove in cars.

519-19=500

So 500 students rode on 10 buses. So now we divide the students onto the buses.

y = 4x + 12
y = 4x − 14
y equals negative one-fourth times x minus 1
y equals negative one-fourth times x plus 7 halves

Answers

Answer:

Step-by-step explanation:

The Answer is A

The equation for a parallel street that passes through the given point is y = 4x + 12

Equation of a line

From the question, we are to determine the equation of the street that is parallel to the first street

NOTE: Two lines are parallel if they have equal slopes.

Thus,

We will determine the slope of the first street.

From the given information,

The street passes through the points (4, 7) and (3, 3)

Using the formula,

Slope = (y₂ - y₁)/(x₂ - x₁)

x₁ = 4

y₁ = 7

x₂ = 3

y₂ = 3

∴ Slope = (3 -7)/(3 -4)

Slope = -4/-1

Slope = 4

Now,

For the equation of the parallel street

The street passes through the point (-2, 4)

Since, the street is parallel to the first street,

Slope = 4

Using the point-slope form

y - y₁ = m(x - x₁)

y - 4 = 4(x - -2)

y - 4 = 4(x + 2)

y - 4 = 4x + 8

y = 4x + 8 + 4

y = 4x + 12

Hence, the equation for a parallel street that passes through the given point is y = 4x + 12

8. A good expression would be -18,492 + -2,516

Answers

The correct options are:

The elevation is 15,976 feet

A good expression would be 18,492 + -2,516

What is the elevation?

When a person goes up a mountain, the sign used to represent their height above sea level is a positive sign (+). When a person goes down a mountain, the sign used to represent their height above sea level is a negative sign (-). So, the sign in front of 18,492 would be positive and the sign in front of 2516 would be negative.

Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given,

The function f(x)=80(1.5)x

Then,

f(4)=80(1.5)4=480

f(8)=80(1.5)8=960

f(0)=80(1.5)0=0

Then the average rate of change between 4 and 8 hours =[tex]\frac{960-480}{4}[/tex]

The average rate of change between 0 and 4 hours=[tex]\frac{480-0}{4}[/tex]

Points on y-axis = (14, -1).

What is a slope?

A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.

How to calculate the slope of a line?

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given points into the formula, we have;

Slope = (6 + 12)/-1 - 14)

Slope = -18/15

Slope = -6/5

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

Where:

x and y are the points.m represents the slope.c represents the intercept.

At point (-12, 14), we have:

14 = -6/5(-12) + c

8 = 72/5 + c

40 = 72 + 5c

5c = 72 - 40

c = 32/5

In conclusion, we can reasonably and logically deduce that the slope-intercept form of the equation of the line described is y = -6x/5 + 32/5.

you would like to investigate whether smokers are more likely than nonsmokers to get lung cancer. you take the students in your class, select half at random and tell them to smoke a pack of cigarettes each day, and you tell the other half not to ever smoke. fifty years from now, you will analyze whether more smokers than nonsmokers got lung cancer. is this an experiment or an observational study? experiment observational study summarize at least three practical difficulties with this planned study.

Answers

According to the question, to investigate through an experiment by telling people to smoke a pack of cigarettes each day by putting their health at risk. This causes serious health issues. And the other half are told not to smoke but might smoke at their own discretion. In the end, it is very difficult to keep track of 50 years of both types of people. That means people who are smoking and others who are not smoking. And, after 50 years, checking their consistency has become extremely difficult, if not impossible. Therefore, this experiment is not possible in both ways, that is, experimental or observational.

jayden's walkie-talkie has a range of 3 miles. jayden is traveling on a straight highway and is at mile marker 253. identify the absolute-value equation and solution to find the minimum and maximum mile marker from 253 that jayden's walkie-talkie will reach.

Answers

Jayden's maximum and minimum walkie-talkie will reach mile marker is:

|x + 253| = 3

x = 253

The range of Jayden's walkie-talkie is three miles.

At mile 253, Jayden is moving straight along a highway.

Find the least and maximum milepost that Jayden's walkie-talkie will reach from 253 by solving the absolute-value equation.

range of 3 miles.

mile marker 253.

Find maximum and minimum of walkie talkie will reach

|x + 3| - 253 = 3x

                   = 253 or x

                   = 250

|x + 3| = 253

      x = 250 or x

         = -256|x - 253|

         = 3

x = 256 or x

  = 250

|x + 253| = 3

x = 253

Therefore, Jayden's minimum and maximum mile marker from 253 that walkie-talkie will reach is

|x + 253| = 3

x = 253

Phrenology is the study of bumps on the head to predict a persons personality or behavior. It was developed in the late 1700s when a German doctor, Franz Gall, discovered that many criminals had particularly bumpy heads. Gall believed that the location of a bump determined characteristics such as kind manners, criminal instinct, or musical talent. Gall primarily studied criminals or hospital patients with oddly shaped heads, and he ignored any evidence that went against his findings. Today, with the use of technology and repeated studies, we know that many different parts of the brain affect a persons personality and behavior.Is phrenology an example of science or pseudoscience?
