Question

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

Answer 1

Correct Answer - C
A = {x, y, z}, B = {u, v, w}
Now, f : `A rarr B`

f is one-one and f is onto.
