LINEAR EQUATIONS
•An algebraic equation in which each term is either
a constant or the product of a constant and a single
variable.
Any equation such that the sum of two solutions is
a solution, and a constant multiple of a solution is a
solution.
FUNCTION


A relationship in which
every input is paired
with exactly one output.
A special type of relation
that pairs each domain
value with exactly one
output value.
FUNCTION NOTATION
A notation that describes a function. For a
function ƒ, when x is a member of the
domain, the symbol ƒ(x) denotes the
corresponding member of the range.
 Use the symbol f (x) to mean the function whose
input is x. “ f(x)” is read “f of x” and means that
the value of the function depends on the value of
x. f(x) is the output (dependent variable) of the
function with input (independent variable) x.

DOMAIN

The set of all possible input values of a relation or
function.
The domain is the set of all the first numbers of
the ordered pairs. In other words, the domain is
all of the x-values.

RANGE
The biggest number subtracts the smallest number.
 The range is the set of the second numbers in each pair,
or the y-values.
 The difference of the greatest and least values in the
data set.

RELATIONS
A
set of ordered pairs.
INDEPENDENT VARIABLE

The input of a function is the Independent
Variable.
DEPENDENT VARIABLE

The output of a function is the dependent
variable. The value of the dependent variable
depends on or is a function of, the independent
variable.
