This statement is incorrect. A mapping diagram can represent both functions and relations. A relation is any set of ordered pairs, while a function is a specific type of relation where each input (or domain element) is associated with exactly one output (or range element). In a mapping diagram, if each input has a single output, it represents a function; if an input has multiple outputs, it represents a relation that is not a function.

Y-axis
It is called the abscissa.
It is called a graph. Graphs consist of many such points.
There is one ordered pair for every arrow in a mapping diagram. The ordered pair represents the mapping from one element in the domain to one element in the codomain.
The answer is 1
A set of ordered pairs, can also be tables, graphs, or a mapping diagram
Ordered pairs are used to locate points on the graph. The first number in an ordered pair corresponds to the horizontal axis, and the second corresponds to the vertical axis.

It is called the abscissa.
The point on a number line that corresponds to a number is called an "ordered pair" of a real number.
It is called a graph. Graphs consist of many such points.
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
By convention, 'x' is almost always the independent variable, but it doesn't have to be.
The following is the answer.
