Function f is a one-to-one function if and only if f is one-to-one and onto at the A. same time. • Function f is an onto function If and only if f(a) = f(b) implies that a = b for В. Function f is a one-to-one correspondence all a and b in the domain of f. if and only if for every element b in the C. codomain there is an element a in the domain, such that b = f(a). Function f is injective Function f is surjective %3D -

Select ALL that applies. f(a)=f(b) implies that a=b, for all a,b in the domain of f. f(a)=f(b) whenever a +b, for all a, b in the domain of f The function is injective and surjective at the same time. If codomain of the function f equal to the rang of f.
