First, see figure 5.3, the graph of g(x)=ln(x). (The parent function) Note the shape and a characteristic point (1,0) on the graph (ln1=0). The graph of the function $-g(x)$ is obtained by reflecting the graph of the parent function g(x)=ln(x) over the x-axis. It passes through (1,0), which is on the axis, but the curve is "flipped"over the x-axis... ... graph (d).
