Answer:

the inequality for the domain of f(x) is [tex]x-3\geq0[/tex]

Step-by-step explanation:

We have been given that [tex]f(x)=\sqrt{x-3}[/tex]

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

[tex]x-3\geq0[/tex]

Therefore, the inequality for the domain of f(x) is [tex]x-3\geq0[/tex]
