    Derivative Problem

    Find f'(x) = 3/(sqrt(x+2))

    How would I approach this problem?

    I'm not sure. It is quite confusing. If it had said, say, "Find f'(x), given f(x) = (something or other)", your task would have been obvious: take the derivative. If it had said "Find f(x), given that f'(x) = (something or other)", your task again would have been obvious: anti-differntiate.

    However, you are being asked to "Find f'(x) = (something or other)". Since they've already given you f'(x), what is there to "find"?

    Please consult with your instructor regarding clarification. Thank you!
