Name 3 ways that a parabola changes with different types of "a" values.

When a is between 0 and 1, the parabola gets wider, when it is greater than 1, it gets narrower, and when it is less than 0 it is reflected across the x-axis.

Up down and side to side on the graph

Step-by-step explanation:

If a is 1, since it is positive the parabola moves up. If a is - 1, since it is negative the parabola moves down. (not sure about side to side because I can't back that one up but I'm 100% sure about up and down)
