Question

The function f(x)=(9x+2)e^-6x has one critical number. Find it. How would I solve this?

Answer 1

critical point we have to find

Answer 2

I know you're supposed to take the derivative first but I'm not sure how for this function. Would it be f'(x) = -6(9x+2)e^-5x ?

Answer 3

no no theses are 2 function

Answer 4

u know product rule ??

Answer 5

Yes, do i apply that?

Answer 6

\[f(x)=(9x+2)*e^{-6x}\]

Answer 7

i think u will get it now

Answer 8

Got it now. Thanks!!

Answer 9

anytime :)

Answer 10

what did you get for f'(x) ?
