What part do you not understand?

anonymous · Answer

I don't understand how to find the answer. My online homework module walked me through a similar problem earlier but when I followed the same steps I came up with an incorrect answer.

I'm assuming I made a mistake but I"m not sure where I went wrong

anonymous · Answer

Alright. What did you get for the derivative? Maybe you computed it wrong.

anonymous · Answer

I think I see where I screwed up. Thanks for replying!

Alright, that's good then.
