This table shows values that represent a quadratic function.
•
What is the average rate of change for this quadratic function for the interval
from x = 3 to x = 5?

Answer 1

-8

Explanation:

The rate of change is found by

f(x2) - f(x1)

-------------------

x2 -x1

We know that f(x2) = -26 when x2 =5

And f(x1) = -10 when x1 = 3

-26 - (-10)

---------------

5 - 3

-26+10

---------------

2

-16/2

-8
