To find the slope of a tangent line to the graph of the function sqrt(x) at the point (4,2), we can use the derivative of the function. The derivative of sqrt(x) is 1/(2*sqrt(x)). Evaluating this derivative at x = 4, we get 1/(2*sqrt(4)) = 1/4. Therefore, the slope of the tangent line at (4,2) is 1/4.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
