"WebTo show that f is injective, suppose that f( x ) = f( y) for some x,y in R^+, then we have 3x^ 2 = 3y^ 2, which implies x^ 2 = y^ 2, since x and y are positive,we can take the square root of both sides to get x = y. Therefore, f is injective,and hence it is a bijection. 27. F(false) : The function f is not invertible because it is not injective. " - Is f x 3x injective

Web4.3 Injections and Surjections. Two simple properties that functions may have turn out to be exceptionally useful. If the codomain of a function is also its range, then the function is onto or surjective. If a function does not map two different elements in the domain to the same element in the range, it is one-to-one or injective.
