Suppose you have 76 feet of fencing to enclose a rectangular dog pen. The function #A = 38x - x^2,# where x = width, gives you the area of the dog pen in square feet. what width gives you the maximum area?
Savannah Andersonthe square root of 76
A perfect square will provide the maximum area. So the square root of 78 will give a width that is equal to the length forming a perfect square.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
