In this video, we provide essential "math help" by explaining how to "graph" "piecewise functions", moving beyond simple ...

Here's the new description with all links and additional text removed: Learn how to graph piecewise functions. A piecewise function is a function which has more than one sub-function for different sub ...

But now, we need to deal with the main problem: What happens if we do have a smooth curve, not a straight line or piecewise-linear graph, and we want to answer the same kinds of questions as we posed ...
