#### Explanation:

Given:

To find relative extrema first **find the first derivative** :

**Find the critical value(s)** by setting

Use the quadratic formula to find the critical value(s):

Find critical points **:**

**Use 2nd derivative** test since it is easy to find the 2nd derivative of this function:
