Which of the following are functions from the indicated domain to the indicatedcodomain? In each case, we represent an element of the domain as anequivalence class and use the notation for equivalence classes in thecodomain. For those relations that are not functions, show that the function isnot well defined by naming an equivalence class in the domain that isassigned two different values.
