 Graph of a Function:  The set of all the points on a coordinate plane whose coordinates makes the rule of function true.
Function: A rule of matching elements of two sets of numbers in which an input value from the first set has only one output value in the second set.
Curve: A set of points that form or can be joined by a continuous line on a graph (See Figures A and B below).
Plot: To place a point on a coordinate plane using its x-coordinate and y-coordinate.
Range: The y-coordinates of the set of points on a graph. Also, the y-coordinates of a given set of ordered pairs. The range is the output in a function or a relation.
Relation: A rule that gives an output number for every valid input number.
y-intercept: The value on the y-axis where a graph crosses the y-axis.
x-intercept: The value on the x-axis where a graph crosses the x-axis.
Domain: The set of x-coordinates of the set of points on a graph; the set of x-coordinates of a given set of ordered pairs. The value that is the input in a function or relation.
