A parabola has a vertex at (-3, 2). Where is the axis of symmetry?

• y = -2

• x = 3

• x = -3

• y = 2

How can you tell the direction of the opening of the graph of a parabola 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

Define Minimum

• The highest y-value on the graph

• Where the parabola touches or intersects the y-axis

• Where the parabola touches or intersects the x-axis, also called the x-intercept

• The lowest y-value on the graph
