2. Determine whether each function is injective, surjective, bijective. Mark and justify your answers. a. f : Z - Z defined by f (n) = n2 f is injective / not injective because f is surjective / not surjective because f is bijective / not bijective b. f : R- - R+ defined by f (x) = x2 f is injective / not injective because f is surjective / not surjective because f is bijective / not bijective
