6.4 Logarithmic Equations and Inequalities

As with the equations in Example6.3.1, much can be learned from checking all of the answers in Example6.4.1analytically. We leave this to the reader and turn our attention to inequalities involving logarithmic functions. Since logarithmic functions are continuous on their domains, we can use sign diagrams. Example 6.4.2. Solve the following ... ................
