4. A motor car race is 500 miles long and consists of completing laps of a circular speedway that has a circumference of 2.5 miles. For which of these functions does y represent the number of miles a motor car
has left to go in the race if x represent the number of laps completed by the motor car?
A. y = -2.5x - 500
B. y = -2.5x + 500
C.
.y = 2.5x -500
D. y = 2.5x + 500

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
