Example 2: The Reciprocal Function
The reciprocal function g is given by the rule g(x) is defined for all nonzero x, but is undefined at x = 0. Find the following values if they are defined: g(0), g(2), g(⅓), g(7/4), g(r + 1). , , . , The graph of the reciprocal function has the equation y = 1/x. This equation can also be written in the form xy = 1. The graph is shown in Figure 1.2.4. Figure 1.2.4
