The graph of f is given. Use the graph to compute the quantities asked for. HINT [See Example 4.]

Example 4:

The graph of a function f is shown in Figure 1. (Recall that the solid dots indicate points on the graph, and the hollow dots indicate points not on the graph.)

From the graph, analyze the following limits.
