The x-value in a function is commonly referred to as the "input" or "independent variable." It represents the value that is fed into the function to produce an output, which is typically called the "y-value" or "dependent variable." In mathematical notation, a function is often expressed as ( f(x) ), where ( x ) is the input.
The Input or X values are called the Domain.
Parameters
A function generally consists of two components: the input (or domain) and the output (or codomain). The input represents the values that are fed into the function, while the output is the result produced after applying the function to the input. Additionally, a function defines a specific relationship or rule that maps each input to a corresponding output.

A graph represents a function if and only if every input generates a single output.
Parameters
A function generally consists of two components: the input (or domain) and the output (or codomain). The input represents the values that are fed into the function, while the output is the result produced after applying the function to the input. Additionally, a function defines a specific relationship or rule that maps each input to a corresponding output.
variables
A function.
For a function, it is the domain.
They are called the arguments of the function.
A function that maps an input onto itself is called an identity function. In other words, the output of the function is the same as the input. The identity function is represented by the equation f(x) = x.
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.
The set of output values of a mapping diagram is called the range. In a function, the range consists of all the values that can be produced by applying the function to its domain. It effectively represents the results or outputs corresponding to each input from the domain.
