Unit 2 Lesson 1: What is a Quadratic Function?
 A quadratic function has a degree of 2, which means that the largest exponent in the equation is always 2.
 The graph of a quadratic function is a ushaped curve called a parabola.
 Parabolas are symmetrical, which means you can fold them in half and each side will match up perfectly.
 Parabolas can open up or down.
