A function is a specific type of relation in mathematics that associates each input value (or domain) with exactly one output value (or range). This means that for every element in the input set, there is a unique corresponding element in the output set. Functions can be represented in various forms, such as equations, graphs, or tables, and are fundamental in understanding relationships between quantities.
A relation is not a function if it assigns the same input value to multiple output values. In other words, for a relation to be a function, each input must have exactly one output. If an input corresponds to two or more different outputs, the relation fails the vertical line test, indicating that it is not a function. For example, the relation {(1, 2), (1, 3)} is not a function because the input '1' is linked to both '2' and '3'.
A function is a mathematical relation that assigns each input value from a set (called the domain) to exactly one output value in another set (called the codomain). The set of output values, often referred to as the range of the function, consists of all values that the function can produce based on its inputs. In essence, a function defines a specific relationship between inputs and outputs, ensuring that each input corresponds to one and only one output.
No, a function cannot have multiple values of ( y ) for one value of ( x ). By definition, a function assigns exactly one output (or value of ( y )) for each input (or value of ( x )). If a relation has multiple ( y ) values for a single ( x ), it is not classified as a function.
No, a function cannot have two output values for the same input value. By definition, a function assigns exactly one output to each input. If an input were to produce multiple outputs, it would violate the fundamental definition of a function.

The set of output values of a function or relation is the range
The Range is the set of all possible output values of a function or relation.
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.

No, not every relation is a function. In order for a relation to be a function, each input value must map to exactly one output value. If any input value maps to multiple output values, the relation is not a function.
No, a function cannot have two output values for the same input value. By definition, a function assigns exactly one output to each input. If an input were to produce multiple outputs, it would violate the fundamental definition of a function.
Range
The co-domain or range.
Good question. A relation is simply that; any x-value to create any y-value. A function, however, cannot be defined for multiple values of x. In other words, for a relation to be a function, it must have singular values for all x within its domain.
