Solution
We are given the function

First, we will find the critical point. To find the critical points, we set f'(x) = 0

Now, we set f'(x) = 0

So we have to split the interval into

We check the intervals

The next interval

The last interval

The graph of the function is given below
The function is increasing on the interval

The function is decreasing on the interval

Local Minimum

Local Maximum
