Functions

Domain

set of allowed input values

Range

set of all possible output values of the function

Codomain

set of output types

Injective

maps different inputs to different outputs

Surjective

if it covers the entire output set (in other words, if the image of the function is equal to the function’s codomain).

Bijective

if it is both injective and surjective. In this case, f is a one-to-one correspondence between the input set and the output set: for each of the possible outputs y ∈ Y (surjective part), there exists exa
