How do I find the axis of symmetry?
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
