Question

I am able to help if you need it, this problem is not that difficult

Answer 1

SOLUTION:

Case: Functions interval

Given: A function graph

Required: To find the region where the graph is increasing

Method:

The region where there is increase is where the graph has a positive slope, i.e. the region where the graph is moving from bottom left to top right.

We see the region on the graph as (-2, -2) to (2, 2)

Picking the x- axis only, this is (-2,2)

Final answer:

The final answer is (-2, 2)
