One Sided Limits

Use one-sided limits to find the limit or determine that the limit does not exist:

limx => 4 16-x^2 / 24-x

The problem might be easier to read like this:

limit 16 - x^2
x --> 4 24 - x

Solution Preview

The function is :

16 - x^2
----------
24 - x

First, look at the limit as x --> 4 from the left (x is less than 4, but is getting closer and closer to 4):

The numerator of the function is going to ...
