Soru 7

Orta Zorluk

Consider the function . For every x 1 , x 2 A if x 1 ? x 2 implies f ( x 1 ) ? f ( x 2 ) then the function f is called one-to-one (or injective). Given a function if the image is equal to the range, i.e. f ( A )= B the function f is called surjective (onto). If a function which is both one-to-one and onto is called a bijection. Constant function and identity function are the concepts related to types of functions. A function assigning each element from its domain a single element in its range is called a constant function. Given A ? , a function defined on the set A and assigning every element of A to itself is called the identity function. Which of the statements above regarding to properties and types of functions is/are correct?

A) III

B) II and III

C) I, III and IV

D) I, II, III and V

E) I, II, III, IV and V
