A rectangular graphical display of categorical data.

• Coefficient of determination

The number r2 or R2 that measures how well a regression curve fits the data

• Factoring (a polynomial)

Writing a polynomial as a product of two or more polynomial factors.

• Fundamental

Theorem of Algebra A polynomial function of degree has n complex zeros (counting multiplicity).

• Graph of an equation in x and y

The set of all points in the coordinate plane corresponding to the pairs x, y that are solutions of the equation.

• Half-plane

The graph of the linear inequality y ? ax + b, y > ax + b y ? ax + b, or y < ax + b.

• Higher-degree polynomial function

A polynomial function whose degree is ? 3

• Implicitly defined function

A function that is a subset of a relation defined by an equation in x and y.

• Initial value of a function

ƒ 0.

• Limit at infinity

limx: qƒ1x2 = L means that ƒ1x2 gets arbitrarily close to L as x gets arbitrarily large; lim x:- q ƒ1x2 means that gets arbitrarily close to L as gets arbitrarily large

• Secant

The function y = sec x.

• Standard unit vectors

In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

A graph in which (x, -y) is on the graph whenever (x, y) is; or a graph in which (r, -?) or (-r, ?, -?) is on the graph whenever (r, ?) is

• Vertical line test

A test for determining whether a graph is a function.

• Yscl
