See%3DFigure 4. Notice that the function is increasing and crosses its tangent line at (1, 5e).NOTE Don't use the Quotient Rule every time you see a quotient. Sometimes it'seasier to rewrite a quotient first to put it in a form that is simpler for the purpose of dif-ferentiation. For instance, although it is possible to differentiate the function1.Question
