Let A = {x, y, z), B = {u, v, w} and f :...

Let A = {x, y, z), B = {u, v, w} and f : A `rarr` B be defined by f(x) = u,
f(y) = v, f(z) = w. Then, f is

A

surjective but not injective

B

injective but not surjective

C

bijective

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
C
A = {x, y, z}, B = {u, v, w}
Now, f : `A rarr B`

f is one-one and f is onto.
