I think it would be A. It controls how much we pay for goods and services, because if there is a high demand, and a limited supply, the cost will be high, if there is a large supply but low demand, then the cost will be lower.

Answer:
v = sqrt(473)
Step-by-step explanation:
v^2 = u^2 +2as
Let u = 9 a = 7 and s = 28
v^2 = 9^2 +2(7)(28)
v^2 = 81 + 392
v^2 = 473
Take the square root of each side
sqrt(v^2) = sqrt(473)
v = sqrt(473)
Problem 1 (on the left)
It appears we have an exponential function curve through the points (0,4) and (1,7)
The general exponential function is of the form
y = a*b^x
The value of 'a' is the y intercept or initial value. So a = 4
Plug in (x,y) = (1,7) to help solve for b
y = a*b^x
y = 4*b^x
7 = 4*b^1
7 = 4b
b = 7/4 = 1.75
Therefore, the function is y = 4*(1.75)^x
- Plug in x = 0 and you should get y = 4.
- Plug in x = 1 and you should get y = 7
These two facts help confirm we have the correct exponential equation.
<h3>Answer: y = 4*(1.75)^x</h3>

Problem 2 (on the right)
The steps will follow the same idea as the previous question.
The exponential curve goes through (-1, 120) and (0,40)
We have a = 40 this time due to the y intercept (0,40)
Plug in the coordinates of the other point to find b
y = a*b^x
y = 40*b^x
120 = 40*b^(-1)
120 = 40/b
120b = 40
b = 40/120
b = 1/3
<h3>Answer: y = 40*(1/3)^x</h3>
