  • The given set of ordered pair subset of $x \times y$ function if same element $a \in x$ is not mapped on to two different elements of y
  • The subset of $x \times $ is a function if it defines a mapping for each element of x an element of y
Since every element of X is mapped to an elements in Y, g is a function
