Question

The domain of the function f(x) = x is ___________.​

Answer 1

Answer:

the domain of f(x)=x is whole of the real number R. The range is also the whole of R.

Answer 2

The domain of the function $f(x) = x$ is R (Real Numbers).​

Explanation:

• A Function is a relation from a set of inputs (domain) to a set of possible outputs (range) where, each input can have only one output.
• A domain of a function is the set of of all possible values that can go in the function.
• In this question, we have to find those values of x which can go into the function to satisfy it.
• Here, all real values can go inside the function as input to satisfy it.

Hence, the domain of the function $f(x) = x$ is the set of Real numbers (R).
