On January 1, 1999, the price of gasoline was $1.39 per gallon. If the price of gasoline increased by 5% per year, what was the cost of one gallon of gasoline, to the nearest cent, 4 years later?

  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).

f(x)=2/3x-8, which give g(x) the greatest value.
