It is known as the domain.
Domain describes all possible input values.
The x-values in a set of points
It is the codomain, often called the range.
An example of a relation that is not a function is the relation defined by the set of points {(1, 2), (1, 3), (2, 4), (3, 5)}. In this relation, the input value 1 corresponds to two different output values (2 and 3), violating the definition of a function, which states that each input must have exactly one output. Therefore, since one input maps to multiple outputs, this relation is not a function.
Yes.

It's domain
The answer is most likely to be "the domain".
The Range is the set of all possible output values of a function or relation.
It is the domain of the relation.
Domain describes all possible input values.
domain
A relation doesn't have an "output value", in the sense that a function does. A set of values is either part of the relation, or it isn't.
The set of values for which the function is defined.
Domain The set of all possible results: range.
X intercepts
The set of output values of a function or relation is the range
