f(x) = x2 + 5x at (4, 36)

    f(x) = x^2 + 5x f '(x) = 2x + 5 f '(4) = 2(4) + 5 = 13

    f ` (x) = 2x + 5 f ` (4) = 13______is the slope at (4,36)

    Calculate the derivative of f(x). Plug in x = 4. What is your exact question about that? Do you know the derivative of x^2? Do you know the derivative of x?
