Answer 1

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: write the given function

`y=f^{^(\prime)}(x)`

STEP 2: Define the points at which a graph is increasing.

We say that a function is increasing on an interval if the function values increase as the input values increase within that interval. The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.

STEP 3: Show the points where the graph was increasing

We write the x coordinates of the intervals, therefore the intervals will be:

`(-2,2)`
