Question

X, Y ⊂: R: f : X arrow Y is a function and f(x) = x': : ∀ x ∈ X then the condition for it to be one-one but not onto is (A) X = Y = R' (B) X = R, Y = R' (C) X = R' , Y = R (D) X = Y = R

Correct answer is (c) X = R' , Y = R

Q. X,Y⊂R:fX→Y is a function and f(x)=x′∀x∈X then the condition for it to be one-one but not onto is

X = Y = R'

X = R, Y = R'

X = R' , Y = R

X = Y = R

Correct answer is (c) X = R' , Y = R

Q. $X, Y \subset R : f X \to Y$ is a function and $f (x) = x^{'} \forall x \in X$ then the condition for it to be one-one but not onto is
