Putting f (x1) = f (x2) we have to prove x1 = x2 Since x1 does not have unique image, It is not one-one Eg: f (–1) = 1 + (–1)2 = 1 + 1 = 2 f (1) = 1 + (1)2 = 1 + 1 = 2 Here, f (–1) = f (1) , but –1 ≠ 1 Hence, it is not one-one Check onto f (x) = 1 + x2 Let f (x) = y , such that y ∈ R 1 + x2 = y x2 = y – 1 x ...

Cantor's first proof that infinite sets can have different cardinalities was published in 1874. This proof demonstrates that the set of natural numbers and the set of real numbers have different cardinalities. It uses the theorem that a bounded increasing sequence of real numbers has a limit, which can be proved by using Cantor's or Richard …
WebInjectivity and surjectivity describe properties of a function. An injection, or one-to-one function, is a function for which no two distinct inputs produce the same output. A surjection, or onto function, is a function for which every element in the codomain has at least one corresponding input in the domain which produces that output.
