## Homework Statement

Find the derivative of the function using the definition of derivative. state the domain of the function and the derivative.

f(x)= x +sqrt(x)

## The Attempt at a Solution

lim f(x)= [x+h+sqrt(x+h) -x -sqrt(x)]/h

h-->0

limf(x)=[h + sqrt(x+h) - sqrt(x)]/h

h->0

not sure how to proceed?
