Question
Write the domain and range of function f(x) given by $\text{f(x)}=\sqrt{[\text{x}]-\text{x}}$
✓
Answer
We know, $\text{f(x)}=\sqrt{[\text{x}]-\text{x}}$ We know that $-1<[\text{x}]<-\text{x}\leq0$ for all $\text{x}\in\text{R}$ $\Rightarrow\sqrt{[\text{x}]-\text{x}}$ is not defined for all $\text{x}\in\text{R}$ $\therefore\ \text{Domain(f)}=\phi$ and $\text{Range(f)}=\phi$
