How you write the domain of a function depends on the type function given. The domain refers to x-values for which the function is defined. The range refers the maximum and minimum y-values. When the function is given as ordered pairs, say: {(-1,1), (0,0),(1,1),(2,4)} The domain in this case is the set of all x-values. Domain: {-1,0,1,2} The range is the set of all distinct y-values. Range: {0,1,2} NB: In listing elements of a set, none should repeat. When the function is given as an equation, say y=x². The domain of this function is all real values, since it is a polynomial.
