Suppose the position function of a moving object is given by $s(x) = \sqrt{x}$. Then the average velocity of the object over the time interval $[2, 2 + h]$ is given by $AV = \frac{\sqrt{2+h} - \sqrt{2}}{h}$. What is the strategy for finding the instantaneous velocity of the object at the exact moment when $x = 2$?
