Question

The range is (- infinity, infinity) and the turning points are (-1.73 , -10.39) and (1.73 , 10.39). What intervals is the function increasing on and decreasing on?

Answer 1

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

STEP 1: Show the increasing and decreasing points of the given graphs

STEP 2: Get the intervals of increment and decrement

For intervals where the function is increasing on, we have:

`(-1.73,1.73)`

For the intervals where the function is decreasing on, we have two intervals which will be combined using the union sign and will be gotten as:

`(-\infty,-1.73)\cup(1.73,\infty)`
