Given the function, fx) = x2-3, calculate the average rate of change of the function from x = 1 to x = 3. -2
4
8
-12

The average rate of change is 4.

Step-by-step explanation:

We are given the function:

And we want to find the average rate of change from x = 1 to x = 3.

The average rate of change is synonymous with the slope. So, we can evaluae the endpoints and find the slope between them.

The first endpoint is:

The second endpoint is:

This yields the two poins (1, -2) and (3, 6). The slope between them will be:

Hence, the average rate of change is 4.
