Answer:

the inequality for the domain of f(x) is
$x-3\geq0$

Explanation:

We have been given that
f(x)=√(x-3)

Domain is the set of x values, for which the function is defined.

So, we find those values of x for which the square root function is defined.

We know that square root function is defined for positive values only.

Hence, we have the inequality

$x-3\geq0$

Therefore, the inequality for the domain of f(x) is
$x-3\geq0$
