and are two sets and function is defined by for all belongs to , then the function is.
one-one
Explanation for correct answer:
Applying the condition of one-one function:
In mathematics, a function from a set to a set assigns to each element of exactly one element of . The set is called the domain of the function and the set is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.
We have the following and
Hence f (x) is one-one but codomain ≠range.
Hence, option(C) is correct.
