Perform the indicated operations if the given changes are made in the indicated examples of this section.

In Example 7, change the logarithm base to 4 and then plot the graph.

Data from Example 7

Plot the graph of y = log₂ x.
We can find the points for this graph more easily if we first put the equation in exponential form: x = 2^y. By assuming values for y, we can find the corresponding values for x.

Using these values, we construct the graph seen in Fig. 13.7.
