What is a parabola and its parts

What shape does the graph of a quadratic equation typically take?

• A circle

• A zigzag pattern

• A U-shape

• A straight line

What is the axis of symmetry in a parabola?

• A point at the top of the parabola

• A diagonal line across the parabola

• A vertical line dividing the parabola into two equal halves

• A horizontal line dividing the parabola

How do you calculate the x-value of the axis of symmetry for a quadratic equation?

• x = -a/(2b)

• x = b/(2a)

• x = -b/(2a)

• x = a/(2b)

What is the vertex of a parabola?

• The highest or lowest point on the parabola

• The point where the parabola intersects the x-axis

• The midpoint of the parabola

• The point where the parabola intersects the y-axis

How is the vertex related to the axis of symmetry?

• The vertex is always to the right of the axis of symmetry

• The vertex is never on the axis of symmetry

• The vertex is always on the axis of symmetry

• The vertex is always to the left of the axis of symmetry

What will be discussed in the next class regarding the vertex?

• How to find the y-value of the vertex

• How to graph the vertex

• How to find the x-value of the vertex

• How to eliminate the vertex

What were students reminded to do with their practice tests?

• Discard them

• Review them with a partner

• Staple them

• Submit them online
