Question

I need help with this problem
--Find the points at which the function has a horizontal tangent line
f(x)=(e^2x)/(x-1)

Answer 1

The function has horizontal tangent lines when the derivative equals zero. What do you have for the derivative?

Answer 2

xe^(2x)/(x-1)^2

Answer 3

You didn't do that quite right. Did you remember to use the quotient rule and the chain rule for (2x) and the (x-1)?

Answer 4

yes could you show me how to do it

Answer 5

i dont know what i did wrong

Answer 6

\(\large f(x)=\large\frac{e^{2x}}{x-1}\)

Answer 7

?

Answer 8

i need to find the points where there is a horizontal tangent line
