Question

If f(x) is equal to the square root of x-3, which inequality can be used to find the domain of f(x)?

Answer 1

f(x) is less than or equal to x-3

Answer 2

Answer:

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

Step-by-step explanation:

We have been given that $f(x)=\sqrt{x-3}$

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 $x-3\geq0$
