part a: complete diagram a so that it is a function.
part b: is it possible to complete diagram b so that it is not a function. if so,
complete the diagram to show a relation, but not a function. if not, justify
your reasoning
part c: is it possible to complete the mapping diagram for diagram c so it
represents a function? if so, complete the diagram to show a function. if
not, justify your reasoning.
