A function relates each element of a set with exactly one element of another set possibly the same set. An example is the limit of x 1 as x goes to 1 is equal to zero because when looking at the graph when the domain x is equal to 1 the range y is equal to zero. Domain rarr function rarr. But in fact they are very important in defining a function.

For example if both the domain and the codomain are the full set of real numbers and the function f is t t 2 then the range will only be those numbers that are zero or positive. The output values are called the range. The range of a function is all the possible values of the dependent variable y.
