If f: A →B is an onto function then range of f is

Let A=7,8,9 and B=7,8,9 and f is onto from A to B, then which of the following is correct?*f is bijectivef is surjectivef may or may not be bijectivef is into function

A function f: A→B is called onto  if  Range = Co-domainGroup startsTrue or False

If a function f(x) is defined from R (real numbers) to R and the range of this function is N. Then the function is onto.Group startsTrue or FalseTrue, unselectedFalse, unselected

If A = {1, 2, 3, 4}, B = (1, 2, 3, 4, 5, 6} are two sets, and the function f: A → B is defined by f(x) = x + 2; for all x ∈A, then the function f is onto.Group startsTrue or FalseTrue, unselectedFalse, unselected

Which of the following function f: Z X Z → Z is not onto?a.f(a, B) = a + bb.f(a, B) = ac.f(a, B) = a – bd.f(a, B) = |b|
