Essay

Consider the equation $\log _{3} x+\log _{3}(x-8)=2$ .
(a) Solve the equation analytically. If there is an extraneous value, what is it?
(b) To support the solution in part (a), we may graph $y_{1}=\log _{3} x+\log _{3}(x-8)-2$ and find the $x$ -intercept.
Write an expression for $y_{1}$ using the change-of-base rule with base 10 , and graph the function to support the solution from part (a).
(c) Use the graph to solve the inequality $\log _{3} x+\log _{3}(x-8)<2$ .
