Chapter 2 - Section 2.2 - The Limit of a Function - 2.2 Exercises - Page 93: 15

There are many possible graphs, this is one example:

Make sure the limit when the function approaches 0 from the left side is -1, and there is an unfilled dot at (0, -1) Make sure the limit when the function approaches 0 from the right side is 2, and there is an unfilled dot at (0, 2) Make sure there is a filled dot at (0, 1); that represents the only place at which the function is defined when x=0
