What is the name of this form:
y = ax² + bx + c

• vertex form
• standard form
• factored form
• zero form

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.

• All parabolas open upward

• All parabolas open downward
