Make the given changes in the indicated examples, and then draw the graphs.

In Example 3, change the 1 to 4 and then make the graph.

Data from Example 3

Construct the graph of x⁴y² = 1 on logarithmic paper. First, we solve for y and make a table of values. Considering positive values of x and y, we have

We plot these values on log-log paper on which both scales are logarithmic, as shown in Fig. 13.24. We again see that we have a straight line. Taking logarithms of both sides of the equation, we have

If we let u = log y and v = log x, we then have 4v + 2u = 0 or u = −2v which is the equation of a straight line, as shown in Fig. 13.24. Note, however, that not all graphs on logarithmic paper are straight lines.
