The inverse function) f -1 ) of  f : A→B is exist if and only if f is  bijection.Group startsTrue or FalseTrue, unselectedFalse, unselected

Every injective function is invertible.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

Let f be the function from{a,b,c,d} to {1,2,3,4} with f(a)=4, f(b)=2, f(c)=1,and f(d)=3,   Then  f is  bijection.Group startsTrue or FalseTrue, unselectedFalse, unselected

Let f be the function from {1, 2, 3, 4} to {1, 4}.with f = {(1, 1), (2, 1), (3, 4)}. Is F a function   Group startsTrue or FalseTrue, unselectedFalse, unselected

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
