A company rents cars. The company charges a fee of $15 per day plus $0.20 per mile. The company also charges $10 per day for insurance. Jerry rented a car for x days. Jerry drove the car 644 miles. Write an equation that could be used to determine the total charge, y, for Jerry to rent the car.

  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).
