In mathematics, an injective function (also known as injection, or one-to-one function) is a function f that maps distinct elements of its domain to distinct elements; that is, f(x1) = f(x2) implies x1 = x2. (Equivalently, x1 ≠ x2 implies f(x1) ≠ f(x2) in the equivalent contrapositive statement.) In other words, every … Visa mer For visual examples, readers are directed to the gallery section. • For any set $${\displaystyle X}$$ and any subset $${\displaystyle S\subseteq X,}$$ the inclusion map $${\displaystyle S\to X}$$ (which sends any … Visa mer • If $${\displaystyle f}$$ and $${\displaystyle g}$$ are both injective then $${\displaystyle f\circ g}$$ is injective. • If $${\displaystyle g\circ f}$$ is injective, then $${\displaystyle f}$$ is injective (but $${\displaystyle g}$$ need not be).

If f ( x 1) = f ( x 2), then 2 x 1 – 3 = 2 x 2 – 3 and it implies that x 1 = x 2. Hence, f is injective. So, x = ( y + 5) / 3 which belongs to R and f ( x) = y. Hence, f is surjective.
