    Question about function

    If f(x) = sqrt(x+4), use a calculator to compute [f(4+h)-f(2)]/h for h =
    0.1, 0.05

    So do I just put f(x) in place of the f's when putting into my calculator and do the negative and positive for each correct?

    \frac{f(4+h)-f(2)}{h}=\frac{\sqrt{(4+h)+4}-\sqrt{2+4}}{h}

    So I need to plug the negative and positive of each number into the function to get the answer?
