Find the domain of each of the following real valued functions of real variable: `f(x)=sqrt(x-2)` (ii) `f(x)=1/(sqrt(x^2-1))` (iii) `f(x)=sqrt(9-x^2)` (iv) `f(x)=sqrt((x-2)/(3-x))`

Explanation

To find the domain of each of the given functions, we need to identify the values of \( x \) for which the function is defined. Let's analyze each function step by step.

### (i) \( f(x) = \sqrt{x - 2} \)

1. **Set the expression under the square root greater than or equal to zero**:
\[ x - 2 \geq 0 \]
