Back

(0,0) is the vertex of the parabola.

Front

Identify the vertex of the parabola represented by the point (3, -4).

Back

(3, -4) is the vertex of the parabola.

Front

What is the axis of symmetry in a parabola?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves.

Front

Back

The axis of symmetry is x = 0.

Front

What are x-intercepts in a parabola?

Back

X-intercepts are the points where the parabola crosses the x-axis.

Front

Identify the x-intercepts for the parabola that crosses at -4 and 0.

Back

The x-intercepts are -4 and 0.

Front

What is a y-intercept in a parabola?

Back

The y-intercept is the point where the parabola crosses the y-axis.

Front
