Note: You can't go through algebra without seeing quadratic functions. The graphs of quadratic functions are parabolas; they tend to look like a smile or a frown. In this tutorial, get introduced to quadratic functions, look at their graphs, and see some examples of quadratic functions!ou can't go through algebra without seeing quadratic functions.

Let's look at the graph. If I look at the graph of y equals x squared you can see it's a smooth curvy parabola shape here's my vertex at 0,0 it goes to the point 1, 1 2, 4 blah blah blah, oops 2, 4 is about there blah blah blah okay so you guys get the general idea of what the graph of y equals x squared looks like.
