6.2 -- Key Features of Quadratic Functions

Key Features

• Vertex

• X - intercept/roots/zeros

• Y - intercept

• Max or Min

• Axis of symmetry

Fill in the Blank

What is the vertex of the function? Write your answer as an ordered pair (x,y) with no spaces.

Multiple Select

Does the graph have a max or a min and what is the value? (Select 2 answers)

• Max

• Min

• -1

• 1

Fill in the Blank

What is the axis of symmetry for the graph? Write your answer as x=# with no spaces.

Multiple Select

Select all of the zeros for the graph:

• (-1,0)

• (5,0)

• (0,5)

• (3,9)

Domain & Range

• For quadratic functions, THE DOMAIN IS ALWAYS -INF,INF

• Range depends on the min/max

Multiple Choice

What is the domain of the graph?

•  $\left(-\infty,\infty\right)$  

• I wasn't paying attention to what Mrs. Kuhlman just said on the last slide

Multiple Choice

What is the range of the graph?

• $\left(-\infty,\infty\right)$

• $\left(-\infty,0\right)$

• $\left(0,\infty\right)$
