WebFor example, if there exist a function f:X→R and defined by fx=x+2 for every x ∈ {1, 2, 3 }, then we can determine the codomain of the function. Thus, f1 =3, f2 =4, f3 =5. When a … WebA function in maths is a special relationship among the inputs (i.e. the domain) and their outputs (known as the codomain) where each input has exactly one output, and the output can be traced back to its input. Types of Functions in Maths. An example of a simple function is f(x) = x 2. In this function, the function f(x) takes the value of ...
