Step-by-step explanation:

Step 1: Define

(-5b² - 8b) - (-9b³ - 5b² - 8b)

Step 2: Simplify

[Distributive Property] Distribute negative:                                                  -5b² - 8b + 9b³ + 5b² + 8b[Addition] Combine like terms (b²):                                                               9b³ - 8b + 8b[Addition] Combine like terms (b):                                                                 9b³

  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.

f(-2) = -3f(1) = 6 . . . estimated from f(x) = (x+2)^2-3, which matches points on the graph (-1,-2) and (0, 1)

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

the table tells us

g(-2) = 1g(1) = 31

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).

It’s d for sure i just did also that’s why
