X = { a,b,c} and Y = {1,2,3,4}. A mapping is given by
a ↦ 1
b ↦ 2
c ↦ 2
Draw the arrow diagram for this function. Write down the set of ordered pairs describing this
function.

  1. X = { a,b,c} and Y = {1,2,3,4}. A relation from X to Y is given by the set of ordered pairs
    {(a,3),(b,2),(b,4),(c,1)}. Draw the arrow diagram. Is it a function? Why?
