Determine whether the function f from { a, b, c, d } to {a, b, c,
d, e} is injective (one-to-one), surjective (onto) and/or bijective
(one-to- one correspondence) :
f(a) = a,
f(b) =
c,
f(c) = b, f(d) = e
a. Is this function injective?
.
surjective?
.
bijective?
.
If your answer is no for any of the
above, explain:
b. Is there an inverse for this function?
.
c. Is the composition f...
