Ignore?
Set
A collection of distinct objects/A collection of "things" (objects or numbers, etc).
Element
An object in a set/Members of a set
Relation
When two things are connected/ A function
Ordered Pair
Two numbers in order, for example (2,4); Two numbers written in a certain order. Usually written in parentheses like this: (4,5)
Arrow Diagram
Used to represent a relation
Domain
The set of first elements of a relation/All the values that go into a function
Range
The set of second elements associated with the first elements (domina) of a relation/ The set of all output values of a function.
Function
A relation where each element in the first set is associated with exactly on element in the second set/a special relationship where each input has a single output.
Independent Variable
A variable whose value is not determined by the value of another variable, and whose value determines the value of another variable/An "input" value of a function.
Dependent Variable
A variable whose value is determiend by the value of another variable/The "output" value of a function.
Function Notation
Notation used to show the independent variable in a function.
Origin
The point where the horizontal axis and the vertical axis intersect
Coordinates
The numbers in an ordered pair that locate a point on a coordinate grid (same as ordered pair)
Vertical Line Test
A visual way to check if a graph shows a function
Rate of Change
The change in one quantity with respect to the change in another quantity (also called a slope)
Linear Relation
A relation that has a straight-line graph
Label
Noun: a word or number used to describe one specific part of a graph Verb: to put a label somewhere
Scale
Numbers written on the axis How much you increase between each mark on the graph
Plot
To put data (information) onto a graph
Cartesian Plane
A 2-dimensional, flat surface. The plane has two mutually axes that meet, at right angles, at a point which is called the origin.
Coordinate
Also called ordered pairs, we write them in the format (x, y)
x-axis
The horizontal axis (left/right)
y-axis
The vertical axis (up/down)
origin
(0,0)
Linear Function
A linear relation whose graph is not a vertical line
Y – intercept
The y-coordinate of a point where a graph intersects the y-axis
X – intercept
The x-coordinate of a point where a graph intersects the x-axis
