    Do you know how to find the derivative of the function? If so then check when the slope is equal to 0.
    To find the derivative use the (f'(x)g(x) - f(x)g'(x))/(g(x)^2)

    If you've "been having trouble with it", then you must have tried something! What have you tried? Exactly where are you having trouble?
