Question

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= 1 to x= 3?​

Answer 1

Answer:


Average rate of change is D. -4

Answer 2

D. -4

Explanation:

Using the general formula,
`m = (f(b) - f(a))/(b - a)` , average rate of change for the quadratic function from x = 1 to x = 3, can be calculated as shown below:

Where,

`a = 1, f(1) = -2`

`b = 3, f(3) = -10`

Plug in the above values in the average rate of change formula:

`m = (-10 - (-2))/(3 - 1)`

`m = (-10 + 2)/(2)`

`m = (-8)/(2)`

`m = -4`

Average rate of change is D. -4
