Terms in this set (...)

algebraic expression
An expression consisting of one or more numbers and variables along with one of more arithmetic operations.
base
In an expression of the form x^n, the base is x.
coefficient
The numerical factor of a term.
coordinate system
The grid formed by the intersection of two number lines, the horizontal axis and the vertical axis.
dependent variable
The variable in a relation with a value that depends on the value of the independent variable.
domain
The set of the first numbers of the ordered pairs in a relation. The input values.
end behavior
Describes how the values of a function behave at each end of the graph.
equation
A mathematical sentence that contains an equal sign, =.
exponent
In an expression of the form x^n, the exponent is n. It indicates the number of times the base is used as a factor.
function
A relation in which each element of the domain is paired with exactly one element of the range.
independent variable
The variable in a function that is subject to change.
like terms
Terms that contain the same variables with corresponding variables having the same exponent.
mapping
Illustrates how each element of the domain is paired with an element in the range.
ordered pair
A set of numbers or coordinates used to locate any point on a coordinate plane, written in the form, (x,y).
order of operations
PEMDAS or GEMDAS
origin
The point where the two axes intersect at their zero points.
power
An expression of the form x^n.
range
The set of second numbers of the ordered pairs in a relation.
reciprocal
The multiplicative inverse of a number.
relation
A set of ordered pairs.
replacement set
A set of numbers from which replacements for a variable may be chosen.
simplest form
An expression is in simplest form when it is replaced by an equivalent expression having no like terms.
solution
A replacement value for the variable in an open sentence.
term
A number, variable, or a product or quotient of numbers and variables.
variables
Symbols used to represent unspecified numbers or values.
vertical line test
If any vertical line passes through no more than one point of the graph of a relation, then the relation is a function.
