Coefficient matrix
A matrix whose elements are the coefficients in a system of linear equations

Cotangent
The function y = cot x

Difference of functions
(ƒ  g)(x) = ƒ(x)  g(x)

Double inequality
A statement that describes a bounded interval, such as 3 ? x < 5

End behavior
The behavior of a graph of a function as.

Equation
A statement of equality between two expressions.

Factoring (a polynomial)
Writing a polynomial as a product of two or more polynomial factors.

Fibonacci sequence
The sequence 1, 1, 2, 3, 5, 8, 13, . . ..

Linear inequality in x
An inequality that can be written in the form ax + b < 0 ,ax + b … 0 , ax + b > 0, or ax + b Ú 0, where a and b are real numbers and a Z 0

Onetoone rule of exponents
