Question

The graph shows the quadratic function f(x) .

What is the average rate of change for the quadratic function from x = 4 to x = 8?

Answer 1

The average rate of change is the change in y divided by the change in x...

(f(8)-f(4))/(8-4)

(4-12)/4

-8/4

-2

So the average rate of change is -2.

Answer 2

(f(8)-f(4))/(8-4)

(4-12)/4

-8/4

-2

the average rate of change is -2.
Hope this helps.
