Question: Graphing a Function w/Interval

There are two parts to this question:

A) Graph the function and approximate any absolute extrema on the given interval.

B) Find any critical numbers, and then use them to find any absolute extrema not located at the endpoints.

Both of these parts have to be done using Maple. I tried asking my teacher again if she could help me through this problem, but she said to figure it out myself, so I have come here for help.

Thanks!

Function: f(x)= squareroot(x+4) * e^((x^2)/10)

Interval: [-2,2]

If anyone could show me the step by step process on how to do this, I would appreciate it. I'm trying to learn this program and I can't seem to grasp a hold of it.
