Such algebraic formulas are the way many people think of functions, though, as the above examples show, such a formula is not required. … So, if we simply refer to the f(x)=x2+1, we probably mean the function f:R→R where f(x)=x2+1.
How do you describe a function?
A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.” The input values make up the domain, and the output values make up the range.

What is a function easy definition?
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. … We can write the statement that f is a function from X to Y using the function notation f:X→Y.

What is a function and not a function?
A function is a relation between domain and range such that each value in the domain corresponds to only one value in the range. Relations that are not functions violate this definition. They feature at least one value in the domain that corresponds to two or more values in the range.
