Question

latethe average rate of change from x = -21 of the function below.x2²+5x-12find the change in y by evaluating theon at-2 and 1:✓mange in y isREF

Answer 1

Answer:

Step-by-step explanation:

The given function is:

`f(x)=x^2+5x-12`

At x = -2:

f(-2) = (-2)² + 5(-2) - 12

f(-2) = 4 - 10 - 12

f(-2) = -18

At x = 1

f(1) = (1)² + 5(1) - 12

f(1) = 1 + 5 - 12

f(1) = -6

The change in y = f(1) - f(-2)

The change in y = -6 - (-18)

The change in y = -6 + 18

The change in y = 12
