-15m^2+8m+12

Step-by-step explanation:

4-5=-1

(3m+2)(5m-6)

15m^2+10m-18m-12

15m^2-8m-12

-1(15m^2-8m-12)

-15m^2+8m+12

  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).

answer: 0.64
