Webb23 aug. 2024 · 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. Here, 2 x – 3 = y. So, x = ( y + 5) / 3 which belongs to R and f ( x) = … WebbA function is bijective if it is both injective and surjective.

Theorem 9.2.3: A … WebbIn mathematical terms, a bijective function f: X → Y is a one-to-one (injective) and onto (surjective) mapping of a set X to a set Y. The term one-to-one correspondence must not be confused with one-to-one function (an injective function; see figures). A bijection from the set X to the set Y has an inverse function from Y to X. chr. gastritis icd 10
