So far, we've only graphed lines... But, there are tons of other things out there to graph. ( I know. This is all VERY exciting! )
Quadratics have graphs called "parabolas."
Here's our most basic quadratic:
He's also our most basic parabola.
I call him Standard Parabola Guy!
Before I show you his graph, let's understand what Standard Parabola Guy does for a living:
He squares things!
He's a squaring machine, baby!
Things go in... and their squares spit out.
We feed x guys into the machine... and y guys spit out.
Let's feed the machine and this will give us the point to graph for Standard Parabola Guy...
