To learn how to evaluate functions (at either numbers, like "-2", or expressions, such as "-2 + h"), try **here**.

Once you've studied the lesson, please attempt the exercise. Don't try to do everything at once. First, evaluate P at x = -2. Then evaluate P at x = -2 + h. Then do the subtraction.

If you get stuck, please reply showing your steps so far. Thank you!
