Work Step by Step
First, see figure 5.3, the graph of g(x)=ln(x). Note the shape and a characteristic point, (1,0) on the graph (ln1=0). The graph of the function g(x)+1 is obtained by shifting the graph of the parent function g(x)=ln(x) UP by one unit. Instead of going through (1,0), it passes through (1,1) ... graph (b).
