The Attempt at a Solution
Im not really sure how to start this problem. I am familiar with how to use the equation above to plug solve for "c" and then plug c into the derivative, so I assume it has something to do with that but I can't find any helpful resources on the web showing me how to do this specific type of problem.[/B]
