Determine the intervals on which the second function to the right is increasing, decreasing, and constant.

? Increasing on (-?, -1); Decreasing on (-1, ?)  

? Increasing on (1, ?); Decreasing on (-?, 1)  

? Increasing on (-?, 1); Decreasing on (1, ?)  

? Increasing on (-1, ?); Decreasing on (-?, -1)

? None of these

Solution

From the we can see that Function is

Increasing on (-1, ); Decreasing on (-, -1)

4th option is correct
