coordinate plane
formed by the intersection of two number lines, the horizontal axis on a coordinate plane.
x axis
the horizontal axis on a coordinate plane
y axis
the vertical axis on a coordinate plane
origin
the point on which the y and x axis intersect
ordered pair
a set of numbers or coordinates, written in the form, (x,y)
x coordinate
the x value of an ordered pair, represents the horizontal placement of the point
y coordinate
the y value of an ordered pair, represents the vertical placement of the point.
discrete graph
a graph that consists of points that are not connected.
continuous graph
a function graphed with a line or smooth curve
relation
a set of ordered pairs
domain
the set of first numbers (x values) of the ordered pairs in a relation.
mapping
illustrates how each element of the domain is paired with an element of the range.
function
a relation in which each element of the domain is paired with exactly one element of the range.
range
the set of second numbers ( y values) of the ordered pairs of a relation
function notation
a way to name a function that is defined by an equation. Replace y with f(x)
