Graphing Quadratics in Vertex Form

What is the main difference between graphing quadratics in vertex form and absolute value graphs?

• Quadratics have no transformations, while absolute value graphs do.

• Quadratics use parentheses squared, while absolute value graphs use straight lines.

• Quadratics are always wider than absolute value graphs.

• Quadratics use straight lines, while absolute value graphs use parentheses squared.

If the 'a' value in the vertex form equation is negative, what transformation occurs?

• Vertical shrink

• Horizontal translation

• Vertical stretch

• Reflection over the x-axis

What does the 'h' value in the vertex form equation represent?

• Reflection over the y-axis

• Vertical stretch

• Horizontal translation

• Vertical translation

How do you determine the vertex of a quadratic function in vertex form?

• By using the values of 'h' and 'k'

• By finding the x-intercept

• By finding the y-intercept

• By setting the equation to zero
