Question

Let

X = {a, b, c}

and

Y = {d, e, f, g}.

Define functions H and K by the arrow diagrams below.

The arrow diagram mapping the Domain of H to the Co−domain of H is given. There are two sets, the set X contains 3 elements, the set Y contains 4 elements, and 3 arrows connect the set X to the set Y, the relation from set X to set Y is labeled H.

The set X contains the elements a, b and c.
The set Y contains the elements d, e, f, and g.
An arrow connects a in the set X to d in the set Y.
An arrow connects b in the set X to f in the set Y.
An arrow connects c in the set X to f in the set Y.

The arrow diagram mapping the Domain of K to the Co−domain of K is given. There are two

(a)

Is H one-to-one? Why or why not?

Is H onto? Why or why not?

(b)

Is K one-to-one? Why or why not?

Is K onto? Why or why not?
