1

Every quadratic function forms a _______ shaped graph called a ______

1) U 2) parabola

2

Parabola goes up if

A>0

3

Parabola goes down if

A <0

4

If a is a proper fraction the graph is

Wide

5

If a is an improper fraction, the graph is

Narrow

6

The line that divides the parabola in half through the vertex

Axis or line of symmetry

7

How do you know if something is a quadratic equation?

If the degree is 2

8

If a is positive the graph opens up and the vertex is called the

Minimum

9

If a is negative and the graph opens down the vertex is called the

Maximum

10

What is the equation for the axis of symmetry ?

X=h

11

Vertex form

Y=a(x-h)+k

12

Intercept form

Y=a(x-p)(x-q)

13

P and q on intercept form are

The x intercepts

14

To calculate the x coordinate of the vertex use (intercept form)

(P+q/2)

15

X coordinate of vertex in standard form

-b/2a
