Does the quadratic have a max/min vertex, and does the parabola open up/down?

• max/ opens down
• min/ opens up
• max/ opens up
• min/ opens down

How can you tell whether a parabola is facing up or facing 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.
• All parabolas open upward
• All parabolas open downward
