Question

Injective function and surjective function

Answer 1

Bijective. Alternatively, f is bijective if it is a one-to-one correspondence between those sets, in other words both injective and surjective. Example: The function f(x) = x2from the set of positive real numbers to positive real numbers is both injective and surjective. Thus it is also bijective.
