How can you tell whether a parabola opens up or opens down by looking at the equation?

• The vertex tells you the direction of the opening

• The value of "a" tells you the direction of the opening. If a > 0, the graph opens up. If a < 0 the graph opens down.

• All parabolas open upward

• All parabolas open downward
