Question

The following figure depicts which type of function?

• A. surjective
• B. bijective
• C. neither injective nor surjective
• D. injective

Answer 1

The correct option is B bijective

The given function is bijective i.e. both one-one and onto.
one – one : Every element in the domain X has a distinct image in the codomain Y. Thus, the given function is one- one.
onto: Every element in the co- domain Y has a pre- image in the domain X. Thus, the given function is onto.
