the vertical and horizontal ranges to read: H-View: -8
By selecting these ranges we ensure that the scale of the graph is kept 1
vertical to 1 horizontal. Press @ERASE @DRAW and you will get the plots of the
natural logarithm, exponential, and y = x functions. It will be evident from the
graph that LN(X) and EXP(X) are reflections of each other about the line y = X.

In this section we present information regarding the PLOT SETUP, PLOT-
