Relations & Functions

Formed by the intersection of two lines, the horizontal axis and the vertical axis - coordinate plane

The horizontal axis on a coordinate plane - x axis

The vertical axis on a coordinate plane - y axis

The four regions into which the XNY axis separate the coordinate plane - Quadrants

The point at which The X axis and Y axis intersect On the coordinate plane (0,0) - origin

A set of numbers are coordinates written in the form of (x,y) - ordered pair

The X value of an ordered pair represents the horizontal placement of the point - x coordinate

A set of ordered pairs - relation

The set of first numbers (x-values) Of the ordered pairs in a relation - domain

The set of second numbers (y-values) Of the ordered Pairs in a relation - range

illustrates how each element of the domain is paired with an element of the range - mapping

A relation in which each element of the domain is paired with exactly one element of the range - function

A Way to name a function that is defined by an equation replace “y” with “f(x)” - function notation

A value substituted for an X value in a function - Input

The result of substituting a value into a function - output

if any vertical line passes through the graph of a relation, no more than once then it is a function - vertical line test

The X intercepts of the graph of a function, the points for which f(x)=0 - Zeros

Arithmetic sequence- A numerical pattern that increase increases or decreases at a constant rate/value

common difference – the difference between consecutive terms in an Arithmetic Sequence

Arithmetic sequence formula- A formula used to find the N4H – term of an arithmetic sequence
