Class Lecture Notes

This lesson covers quadratic functions: first, we look at what they look like, and then we see how to plot them using code.

First, we plot the simplest one, y = x². Move the vertex down by one unit and see how the entire curve moves accordingly. Then, overlay one that opens downward for comparison.

On the left is the code for the three curves we just saw. First, look at the two lines for sampling—they determine how smooth the curve is. Then, look at the plotting section; each curve is just one plot command.

There are three key points in this lesson; you can practice them on your own after class.
