It is the x of my vertex

The minimum point is the ________?

Lowest point on the graph

What is the vertex?

The highest or lowest point on the graph

The maximum height is always the ___ of your vertex.

Y

What letter determines if the graph is going up or down?

a

THE DOMAIN OF A PARABOLA IS ALWAYS

all real numbers

A quadratic equation is written in the form

ax^2 + bx + c

What letter tells me my Y-intercept

c

If the graph has a maximum, it opens_____?

down

How many solutions can a quadratic have?

no more than 2

Solutions, Roots, x-intercept, and zeros are all the

same

If the graph has one solution,

the only point the parabola touches the x-axis is at the vertex.

If the graph has no solution,

the parabola DOES NOT cross the x-axis

If the graph has two solutions,

the parabola crosses the x-axis at two points.

If the graph has a minimum, it opens_____?

up

What is the vertex of this equations? y=4(x+6)-1

(-6,-1)

What is the vertex of this equations? y=2(x-4)+2

(4,2)

What does it mean if it asks for the zeros?

Where does it cross the x-axis

What is a root?

Where does it cross the x-axis

What is an intercept?

Where it crosses one of the axis

If you have a word problem that asks you "Where does the ball hit the ground?" What would you look for in your calculator

Where it crosses the x-axis

What is the y-intercept?

Where the graph crosses the y-axis
