1
Quadratic Functions

3
How Parabolas Open A parabola will open upward if the value of a in your equations is positive-this type of parabola will have a minimum A parabola will open downward if the value of a is negative-this type of parabola will have a maximum

4
Vertex The maximum and minimum point of a parabola is called the vertex The vertex is the lowest or highest point on the parabola

5
Symmetry All parabolas will have a line of symmetry The line of symmetry of a parabola is called the axis of symmetry The axis of symmetry separates the parabola so that each side is identical to the other

6
Axis of Symmetry

7
Graphing Parabolas by Hand

8
Practice

9
Solutions to Quadratic Equations Solutions to quadratic equations are called roots or zeros. The roots or zeros are also known as x- intercepts.

10
Solutions to Quadratic Equations You can have two roots, double roots, or no real root solutions to quadratic equations When would you expect to see – Two roots? – Double roots? – No real roots?

11
Find the Roots
