A relationship between input and output. function
Two numbers whose product is one. It is the same as multiplicative inverses. reciprocals
A set of numbers, or coordinates, written in the form (a, b). ordered pairs
A number, variable, or a product or quotient of numbers and variables separated by addition or subtraction. term
In a relation, the set of first numbers of the ordered pairs. domain
It represents the horizontal placement of a point on a coordinate graph. x-coordinate
Used to determine if a graph represents a function. vertical line test
Finding the value for a variable that makes a mathematical sentence true. solving
An expression like x^n where x is the base and n is an exponent. power
The rule that lets you know which operation to perform first when evaluating an expression. order of operations
Formed by the intersection of two number lines, the x-axis and the y-axis. coordinate system
Each object or number in the replacement set. element
In a relation, the variable with a value that is dependent on the value of the independent variable. dependent variable
A function with a graph that is not a straight line. nonlinear function
Letters or symbols used to represent unspecified numbers or values. variables
Indicates the number of times the base is used as a factor. exponent
In a relation, the set of second numbers of the ordered pairs. range
Two numbers whose product is one. It is the same as reciprocals. multiplicative inverses
A set of ordered pairs. relation
The vertical number line in a coordinate plane. y-axis
A graph that consists of points that are not connected. discrete function
An equation that is true for every value of the variable. identity
The numerical factor of a term. coefficient
Quantities being multiplied. factors
The result of a multiplication expression. product
The set if elements from the replacement set that make an open sentence true. solution set
A mathematical sentence that contains an equal sign. equation
The point where the x-axis and y-axis intersect. origin
A function graphed with a line or smooth curve. continuous function
Expressions that represent the same value. equivalent expressions
A set of numbers from which replacements for a variable may be chosen. replacement set
Consists of sums and/or products of numbers and variables. algebraic expressions
A mathematical statement that contains algebraic expressions and symbols. open sentence
The product of 1 and a number is equal to the number. multiplicative identity
It represents the vertical placement of a point on a coordinate graph. y-coordinate
In a power it is the number being multiplied repeatedly as a factor. base
In a relation, the variable whose value determines the output. independent variable
An expression that contains no like terms or parentheses. simplest form
A collection of objects or numbers that is often shown using braces. set
To find the value of an expression. evaluate
The horizontal number line in a coordinate plane. x-axis
The sum of any number and 0 is equal to the number. additive identity
The plane formed by the x-axis and the y-axis. coordinate plane
Terms that contain the same variables, with corresponding variables having the same power. like terms
