Take the first derivative and find that critical number, guurl!

f'(x)=7e^-(6x)-6(7x+5)e^-(6x)

By definition, you say that x = n (where n is some number), is a critical point of the function, f(\(x\)) if f(\(n\)) exists and if either of the following is true: f'(c) = o \(\large OR\) f'(c) = D.N.E

Sorry I meant to say f(\(n\)) not f(\(c\)) for that definition
