If f (x) = StartRoot x minus 3 EndRoot, which inequality can be used to find the domain of f(x)? StartRoot x minus 3 EndRoot greater-than-or-equal-to 0
x minus 3 greater-than-or-equal-to 0
StartRoot x minus 3 EndRoot less-than-or-equal-to 0
x minus 3 less-than-or-equal-to 0

Given:

The function is:

To find:

The inequality that is used to find the domain of the given function.

Solution:

We have,

We know that the radical functions are defined for only positive values of radicand.

It means the given function is defined if the value of (x-3) is greater than or equal to 0.

Adding 3 on both sides, we get

The inequality is used to find the domain of the given function and the domain of the given function is .

Therefore, the correct option is B.
