how do you find the rate of change in a square root function
--------------------------------------------------- 

The instantaneous rate of change of the function f(x) is the derivative of this function f'(x).


The average rate of change of the function f(x) is this ratio   %28f%28x%5B2%5D%29+-+f%28x%5B1%5D%29%29%2F%28x%5B2%5D+-+x%5B1%5D%29.


The average rate of change of the function  sqrt%28x%29  is this ratio   %28sqrt%28x%5B2%5D%29+-+sqrt%28x%5B1%5D%29%29%2F%28x%5B2%5D+-+x%5B1%5D%29.
