• x= -1

• x = 2

• y = -1

• x = -2

What is the vertex for f(x)=4(x-2)² + 3

• (-2, 3)

• 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
