A function that can be written in the form f(x) = ax²+bx+c, where a,b,and c are real numbers and a ≠ 0
The graph of a quadratic function that is U-shaped and contains a vertex that is a maximum or minimum, depending on if the graph goes up or down.
Parabola
The line of symmetry that runs through the vertex; can be found algebraically: x=-b/(2a)
Axis of Symmetry
All the output values of a function.
range
events such that the outcome of one event does not affect the probability of the outcome of another event
independent events
a number from 0 to 1 inclusive or a percent from 0% to 100% inclusive that indicates how likely an event is to occur
probabilty
a collection or list of items
set
a diagram that shows how two or more sets in a universal set are related
Venn diagram
a possible result of an experiment
outcome
The intersection of the sets of A and B, written A∩B, is the set of elements that are in both A and B.
intersection of sets
the probability that two or more independent events will occur together is the product of their individual probabilities
Multiplication Rule
The distance across a circle through its center. The line segment that includes the center and whose endpoints lie on the circle.
diameter
Theorem that states that in a right triangle, the square of the sum of the legs of the triangle is equal to the square of the hypotenuse.
Pythagorean theorem
Is the set of points which are all the same distance (its radius) from a certian point( the center).
circle
a figure formed by the intersection of a plane and a right circular cone.
conic section
an unbroken part of a circle

Major arcs
a portion of the circumference of the circle
Arc Length
a segment whose endpoints are on a circle
chord
The point of intersection of the perpendicular bisectors of the sides of a given triangle; the center of the circle circumscribed about a given triangle.
