The domain of f(x) is (0, +∞), and the range is (0, +∞). The graph of the function will have a vertical asymptote at x = 0 and will continuously increase as x approaches positive infinity.
To graph the given logarithmic function f(x) based on the table, we can use the information provided. The table presents pairs of values (x, y), where x represents the input and y represents the output of the function.
From the table, we can observe that the input values (x) are positive and non-zero. This indicates that the domain of the function is x > 0, meaning x is greater than zero. In interval notation, the domain would be written as (0, +∞).
Looking at the output values (y) in the table, we see that they are all positive. This suggests that the range of the function is y > 0, meaning y is greater than zero. In interval notation, the range would be expressed as (0, +∞).
Graphically, the function f(x) is logarithmic and will have a vertical asymptote at x = 0. As x approaches positive infinity, the function increases without bound. The graph starts at y = 125 when x = 1, and it intersects the y-axis at y = 5 when x = 1.5. The graph of the function will resemble a curve that approaches but never touches the x-axis.

Team A and Team B together won 50% more games than Team C did. Team A won 50% as many games as Team B did. The three teams won 60 games in all. How many games did each team win?
Answers
Let x be the number of games won by Team A.
Let y be the number of games won by Team B.
Let z be the number of games won by Team C.
From the given information, we can form the following equations:
Equation 1: x + y + z = 60 (The total number of games won by the three teams is 60.)
Equation 2: x = (1/2)y (Team A won 50% as many games as Team B.)
Equation 3: x + y = 1.5z (Team A and Team B together won 50% more games than Team C.)
Now, let's solve this system of equations:
Substituting Equation 2 into Equation 3, we get:
(1/2)y + y = 1.5z
(3/2)y = 1.5z
y = (1.5z) * (2/3)
y = z
Substituting y = z into Equation 1, we have:
x + y + z = 60
x + y + y = 60
x + 2y = 60
Substituting y = z into Equation 3, we have:
x + y = 1.5z
x + y = 1.5y
x = 0.5y
Now, we can substitute x = 0.5y and y = z into Equation 1:
0.5y + 2y = 60
2.5y = 60
y = 60 / 2.5
y = 24
Substituting y = 24 into x = 0.5y:
x = 0.5 * 24
x = 12
Substituting y = 24 into the equation y = z:
z = 24
Therefore, Team A won 12 games, Team B won 24 games, and Team C won 24 games as well.

The expression (3√2) / (3√6) with a rationalized denominator is 3√9 / 6. Option C is the correct answer.
To rationalize the denominator in the expression (3√2) / (3√6), we can multiply both the numerator and denominator by the conjugate of the denominator. The conjugate of √6 is -√6, so we multiply the expression by (-√6) / (-√6):
(3√2 / 3√6) * (-√6 / -√6)
This simplifies to:
-3√12 / (-3√36)
Further simplifying, we have:
-3√12 / (-3 * 6)
-3√12 / -18
Finally, we can cancel out the common factor of 3:
- 3√9 / - 6.
Simplifying further, we get:
3√9 / 6.
Option C is the correct answer.

Answers
Step-by-step explanation:
a linear relationship or function is described in general as
y = f(x) = ax + b
Because the variable term has the variable x only with the exponent 1, this makes this a straight line - hence the name "linear".
here f(x) is P(x) :
P(x) = ax + b
now we are using both given points (ordered pairs) to calculate a and b :
20 = a×170 + b
2820 = a×220 + b
to eliminate first one variable we subtract equation 1 from equation 2 :
2800 = a×50
a = 2800/50 = 280/5 = 56
now, we use that in any of the 2 original equations to get b :
20 = 56×170 + b
b = 20 - 56×170 = 20 - 9520 = -9500
so,
P(x) = 56x - 9500
