For each piecewise linear function:

a. Draw its graph (by hand or using a graphing calculator).

b. Find the limits as x approaches 3 from the left and from the right.

c. Is it continuous at x = 3? If not, indicate the first of the three conditions in the definition of continuity (page 80) that is violated.
