Definition: Vertical line
going through the parabola
and the vertex
Vertex
Definition: The
lowest or highest
point on the parabola
Parabola
Definition: A U
shaped
symmetrical curve,
formed like an arch
Minimum
Definition: The
lowest point of the
parabola, when the
parabola is opened
up
Maximum
Definition: The highest
point of the parabola
when the parabola is
upside down
X-Intercepts
Definition: Points where
parabola passes the x-axis.
Y-Intercepts
Definition: Point where
parabola passes the y-axis
Zeros of the function
Definition: Also known as the "roots"
of the parabola. An input value hat
produces and output of zero
Roots of the Equation
Although roots are known as the zeros the difference
is that zeros is in function and roots is in equations.
The roots of an equation are where the parabola
passes the x-axis and is the solution to the equation.
End Behavior
Definition: The behavior of
the graph as "x" approaches
positive infinity or negative
infinity

Definition: Expression given from
under the square root sign in teh
quadratic formula.
Difference of squares
Definition: The subtractions of two squares
terms is a squared term minus from another
squared term
Perfect square trinomial
Definition: Consists of the square of the first
term of binomial, double the product of
binomial's first and last term, and the square of
the last term of binomial
Factors of a Quadratic
Definition: Finds the
roots or x-intercepts of
the quadratic
equation.
