Question 53059
Here is an example:

Find the range of the funcion f : x = 2x + 1 if the domain is ( -1 , 0 , 1 , 2)

-1 =          -1
0 =            1
1 =            3
2 =            5
Domain              Range

The above 'diagram' shows that the range is ( -1 , 1 , 3 , 5)

Dictionary Definitions

Domain : The domain of a function is the set of all input values to the fraction.

Range : A function is a relation, such that each element of a set (the domain) is associated with a unique element of another (possibly the same) set (the codomain, not to be confused with the range). The concept of a function is fundamental to virtually every branch of mathematics and every quantitative science.
