Question

The function f(x) = (7 x+5)e^(-6 x) has one critical number at x=?

Answer 1

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

Answer 2

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

Answer 3

what is the critical number? I completely forgot

Answer 4

like what part of it?

Answer 5

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

Answer 6

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

Answer 7

Thank you! this helped a lot! ;)
