WebFeb 23, 2024 · Step 3: The numerator of equation (12) is zero at x = 2 and this value is not a restriction. Thus, 2 is a zero of f and (2, 0) is an x-intercept of the graph of f, as shown in Figure 3.17.3.12. Step 4: Note that the rational function is already reduced to lowest terms (if it weren’t, we’d reduce at this point).
