Answer:
Explanation:
To find the average rate of change of the function f(x) from -5 to -2, we need to calculate:
(f(-2) - f(-5))/(-2 - (-5))
First, let's find f(-2) and f(-5):
f(-2) = (-2)^2 - 4 = 0
f(-5) = (-5)^2 - 4 = 21
Substituting these values in the above formula, we get:
(0 - 21)/(-2 + 5) = -21/3 = -7
Therefore, the average rate of change of f(x) from -5 to -2 is -7.
So the answer is (C) -7.
