a combination of two functions such that the output from the first function becomes the input for the second function

The set of input values of a function or relation, usually "x" coordinates.

1. A relationship from one set (called the domain) to another set (called the range) that assigns to each element of the domain exactly one element of the range. 2. The action or actions that an item is designed to perform.

a variable (often denoted by x ) whose variation does not depend on that of another.

The simplest, most general function in a family of functions.

The set of output values of a function. Usually the y coordinates.

a set of pairs of input and output values

an expression that uses brackets to describe subsets of real numbers

two functions f and g are inverse functions if and only if both of their compositions are the identity function

The distance a number is from zero on a number line. ALWAYS POSITIVE

a function written in the form y = /x/, and the graph is always in the shape of a v

A line that divides a plane figure or a graph into two congruent reflected halves

an apparent solution that must be rejected because it does not satisfy the original equation

a point you pick on one side of the boundary of the graph of a linear inequality; if the point makes the inequality true, all the points in that half-plane are solutions
