In order to find the critical points, you need to find the derivative, *f'* of the function.

#### Explanation:

Here, you do so by applying the quotient rule.

When you apply the quotient rule, you should obtain the equation of

Solve for zeros

Then, plug in the values that make x zero into the original equation and you should obtain a max point of (-0.239,6.254)
