Answer:
Step-by-step explanation:
When figuring out the graph of a sinusoidal, I keep in mind the acronym FPARHM:
F - function (sine or cosine)
P - period
A - amplitude
R - reflections
H - horizontal/phase shift
M - midline
Looking at the graph, we can figure out that the function is sine (since it intersects the origin at its midpoint, the period is [tex]\pi[/tex] (because it repeats every [tex]/pi[/tex] units in the x-direction, the amplitude is 2 (because the graph's extreme points are 2 units away from the midline in the y-direction, there are no reflections, no horizontal/phase shift, and the midline is [tex]y=0[/tex] (since the graph isn't shifted up or down in the y-direction.
Finally, knowing all these parts, we can piece together the equation of the sinusoidal graph. In general, the equations of sinusoidal graphs are in the form [tex]y=a\sin(bx+c)+d[/tex] where [tex]|a|[/tex] is the amplitude, [tex] \frac{2\pi}{|b|}[/tex] is the period, [tex] \frac{c}{b}[/tex] is the horizontal shift, and [tex]d[/tex] is the midline. Additionally, if [tex]a[/tex] is negative, the graph needs to be reflected over the x-axis and if [tex]b[/tex] is negative, the graph needs to be reflected over the y-axis. Knowing this, all we need to do is plug in the amplitude, period, phase shift, and midline to the equation. The equation is [tex]y=2\sin(2x)[/tex]
Hope this helps :)
If f(x)=3x−1 and f(a)=−43, what is the value of a ??
Answer:
a = -14
Step-by-step explanation:
f(a) = -43
3a - 1 = -43
3a = -43 + 1
3a = -42
a = -42/3
a = -14

Answer:
A
Step-by-step explanation:
If y is a function of x, then the equation for y would be y=Ix(+or-or*or%) to nI
For this specific event, the proper equation would be y=Ix-0.5I
Breaking down this equation, y equals the absolute value of x-0.5.
So if x was 2, it would go as y=I2-0.5I where y equals 1.5.

The function f(x) = x2 is translated 7 units to the left and 3 units down to form the function g(x). Which represents g(x)?
A. g(x) = (x − 7)2 − 3
B. g(x) = (x + 7)2 − 3
C. g(x) = (x − 3)2 − 7
D. g(x) = (x − 3)2 + 7
Answer:
B. g(x)=(x+7)^2-3
Step-by-step explanation:
Vertex form is F(x)= a(x-h)^2+k
a is the reflection
h and k are the vertex (x,y) = (h,k)
in this case there is no shrink or stretch (a)
if it is translating left or right it is "h". In this case it is translated left so its -7. However if you look at vertex form it is "x-h" so -7-7= +7
If it translating up or down it is "K". In this case it is translated down so its -3.
If it was translated up or right then its positive. If it was translated down or left its negative.
After you figure out what h and k are then you just plug it in. h=-7, k=-3
so the answer in vertex form is, g(x)=(x+7)^2-3

Let R(x) =X-3/x-4. Solve for R(x) <= 0.
The value of x in the function r(x) = x - 3/x-4 is equal is 3.
To solve this problem, all that is required from us is simply substitute the values and solve for the value of x.

R(x) = x-3/x-4R(x) = 0What is a Function?A function from a set A to a set B assigns to each element of A exactly one element of B. The set A is usually the domain of the function while the set B is the codomain of the function.
Given that the function R(x) is
[tex]R(x) = \frac{x-3}{x-4}[/tex]
And also, R(x) is equal to 0.
[tex]R(x) = \frac{x-3}{x-4}\\ 0= \frac{x-3}{x-4} \\0(x-4) = x - 3\\0 = x- 3\\x = 3[/tex]
The value of x in the function is 3.

Answer:
m<B = 141 degrees
Step-by-step explanation:
This shape is a heptagon meaning its angles should have a sum of 900 degrees.
we are given the degrees and we need to ad them up
148+90+120+129+130+142=749
then we subtract 749 from 900 which looks like
900-749=141
from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees
juan rolls a fair number cube twice what is the probability that he will roll an odd number on the first roll and an even number in second
Answer:
1/4
Step-by-step explanation:
[tex]\mathsf{Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ outcomes}}[/tex]
Assuming the number cube has faces number 1 through 6, the probability of rolling any of the number is 1/6.
Therefore,
P(odd number) = P(1) or P(3) or P(5)
= 1/6 + 1/6 + 1/6
= 3/6
= 1/2
Similarly,
P(even number) = P(2) or P(4) or P(6)
= 1/6 + 1/6 + 1/6
= 3/6
= 1/2
⇒ P(odd) AND P(even) = 1/2 × 1/2 = 1/4

Answer:
(x + 8)² + (y - 3)² = 64
Step-by-step explanation:
(x - (-8))² + (y - 3)² = 8²
(x + 8)² + (y - 3)² = 64
