Quadratics
- Axis of Symmetry
- A line through a shape so that each
side is a mirror image. When the shape
is folded in half along the axis of
symmetry, then the two halves match
up.

- Vertex
- The vertex is the minimum
or the maximum of the
quadratic equation.

right circular cone with a plane parallel to a
generator of the cone

- Minimum
- The minimum is the vertex when the parabola
opens up and the vertex is the lowest point.
- It can be found
with 2 of the
quadratic
equations:
ax^2+bx+c,
a(x-h)^2+K, or by
graphing the
parabola

- Maximum
- The maximum is the vertex
when the parabola opens
down and the vertex is the
highest point
- It can be found
with 2 of the
quadratic
equations:
ax^2+bx+c,
a(x-h)^2+K, or
by graphing
the parabola
- X-intercepts
- The x-intercepts, roots, or
zeroes, are the points in
which the quadratic
crosses the x-axis
- The easiest way to find the
x-intercepts is to graph the
parabola, but using the
factored form equation
(x-+h)(x-+k), h and k would be
the x-intercepts, but with
opposite signs

- Y-intercept
- The y-intercept is the point at
which the quadratic crosses the
y-axis
- Equation to find the
y-intercept=ax^2+bx+c,

- Zeros of the Function
- The zero of a function is the x-value
that makes the function equal to 0

- The easiest way to do this is to put
your equation into standard form,
(x)=ax^2+bx+c. Then you write in 0
where (x) is, then solve for x. That
gives you the zero of the function
- Roots of the Equation
- The roots of the equation are the x-values of the equation
- The easiest way to find
the x-intercepts is to
graph the parabola, but
using the factored form
equation (x-+h)(x-+k), h
and k would be the
x-intercepts, but with
opposite signs
- End Behavior
- The appearance of a graph as
it is followed farther and
farther in either direction. For
polynomials, the end behavior
is indicated by drawing the
positions of the arms of the
graph, which may be pointed
up or down. Other graphs
may also have end behavior
indicated in terms of the
arms, or in terms of
asymptotes or limits.
