23.1.5 The Simplest Quadratic, y=x²

Core idea

Make a table, plot the points, and watch y=x² trace a symmetric 'bowl' so you can first see what it looks like.

Module goal. Pick up the family of functions you've already met, get to know quadratics as a new member, and build their algebraic definition.
