This lesson covers quadratic functions: first look at what they look like, then see how to draw them with code.

Start with the simplest y = x². Move the vertex down one unit and see how the whole curve moves with it. Then overlay a downward-opening one for comparison.

On the left is the code for those three curves. First look at the two sampling lines—they determine how smooth the curve is. Then look at the drawing part: each curve is just one plot call.

The three key points of this lesson—you can practice them when you review.
