Question

The table shows for a quadratic function.

what is the average rate of change for this function for the interval from from x=3 to x=5

Answer 1

the average rate of change is 12

Explanation:

The computation of the average rate of change is shown below:

As from the attached table

f(b) = f(5) = 32

f(a) = f(3) = 8

Now the average rate of change is

= (32 - 8) ÷ ( 5 - 3)

= (24 ÷ 2)

= 12

Therefore the average rate of change is 12

So the same is relevant and considered too
