let f(x) =` sqrtx` and g(x) =x be function defined over the set of non negative real numbers . find (f+g)(x) , (f-g)(x) , (fg)(x) and (f/g)(x) .

Explanation

To solve the problem, we need to find the following expressions based on the functions \( f(x) = \sqrt{x} \) and \( g(x) = x \):

1. \( (f + g)(x) \)
2. \( (f - g)(x) \)
3. \( (fg)(x) \)
4. \( \left(\frac{f}{g}\right)(x) \)

Let's go through each step one by one.
