Find the derivative of the function below in two ways.
F(x) = (x - 7 x sqrt(x)) / sqrt(x)

(a) By using the Quotient Rule.
(b) By simplifying first.

  • calculus -

    Can't you do either of these? Do you know the quotient rule?

    If you simplify first, you get
    F(x) = sqrt x - 7x

    Try differentiating that term by term. There are only two terms.

    Someone will gladly critique your work.
