The domain of the function f(x)= x (1+x^2) is: - Vidyadip

MCQ

The domain of the function $\text{f}(\text{x})=\frac{\text{x}}{(1+\text{x}^2)}$ is:

A
$R - \{1\}$
B
$R - \{-1\}$
✓
$R$
D
None of these

✓

Answer

Correct option: C.

$R$

Given, function $\text{f}(\text{x})=\frac{\text{x}}{(1+\text{x}^2)}$
Since $f(x)$ is defined for all real values of $x$
So, domain $(f) = R.$
