( 0 , -1 )

What is the y-intercept of this function?

down

Does this parabola open up or down?

maximum; the max is 3 when x=0

Does this parabola have a maximum or minimum?what is that value?

( 0 , 3 )

What is the y-intercept of this function?

x = 0

What is the axis of symmetry?

( 0 , 3 )

What is the vertex?

up

Does this parabola open up or down?

minimum; the min is 0 when x = 3

Does this parabola have a maximum or minimum?What is that value?

x = 3

What is the axis of symmetry?

( 3 , 0 ) - only one root

What are the roots, zeros, x-intercepts, or solutions of this function?

( 3 , 0 )

What is the vertex?

up

Does this parabola open up or down?

minimum

Does this parabola have a maximum or minimum?

( 0 , -12 )

What is the y-intercept of this function?

up

Does this parabola open up or down?

minimum; the min is 1 when x = 2

Does this parabola have a maximum or minimum?What is that value?

( 0, 4 )

What is the y-intercept of this function?

x = 2

What is the axis of symmetry?

none; this parabola does not cross the x-axis therefore it has no real solutions.

What are the roots, zeros, x-intercepts, or solutions of this function?

( 2 , 1 )

What is the vertex?

down

Does this parabola open up or down?

maximum; the max is 4 when x = -2

Does this parabola have a maximum or minimum?What is that value?

( 0 , 0 )

What is the y-intercept of this function?

x = -2

What is the axis of symmetry?

( 0 , 0 ) and ( -4 , 0 )

What are the roots, zeros, x-intercepts, or solutions of this function?
