There is a lot of vocabulary you need to know for quadratics!

ZEROS: These are known as the x-intercepts or solutions of the graph.

MAXIMUM: This is the highest value of a parabola on the y-axis.

VERTEX: The vertex is the ordered pair located at the highest or lowest point of the parabola.

AXIS OF SYMMETRY: The axis of symmetry is the equation that cuts the parabola in half. The equation is written as x = # it cuts through.

• A

• B

• C

• D

Remember, ZEROS are known as the X-INTERCEPTS of the graph.

• Zeros: -1 and -3

• Zeros: -1 and 3

• Zeros: -3 and 3

• Zeros: 1 and -4

Vocabulary you need to know:

AXIS OF SYMMETRY: The axis of symmetry is where it cuts the parabola in half and is written as an equation x = # it cuts through.

ZEROS: The zeros are the x-intercepts of the graph.
