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

If the a value is positive in the equation of y = ax² + c, which direction does the graph open?

• up

• down

• left

• right
