Thread: Defintion of derivative

How do you get the derivative of 2(x)^(1/2) using the definition of derivative?

you use the quotient differnece if you know what that is?

Yeah, but I always seem to get confused on how to fit f(x) into
f '(x)=f(x+h)-f(x)/h

first off remeber it is the lim as x goes to o and in this case f(x+h)= and f(x)= ...so it would be the limit of that as h goes to 0
