The graph of f is shown at the right. Interactive graphs/plots help visualize and better understand the functions. Note that as the points get closer together, the slope of the line approaches the slope of the curve. It is possible for this limit not to exist, so not every function has a derivative at every point. The second derivative at C 1 is positive (4.89), so according to the second derivative rules there is a local minimum at that point.
