If f(x)=sqrt1/2x-10+3 which inequality can be used to find the domain of f(x)

Correct choice is the 3rd choice .

Step-by-step explanation:

Given function is .

Now we need to find about what is the inequality that can be used to find the domain of function f(x).

We know that square root function is defined for positive valuses or 0 then expression inside square root must be greater or equal to 0

Hence correct choice is the 3rd choice .

Step-by-step explanation:

The given function is a radical function which is defined as those function which has the independent variable inside a root.

The presence of that root implies a restriction for the domain, because all square roots just can result in a positive expression, this means that the whole expression inside the root must be equal or more then zero, that is

Otherwise, the function won't be defined, because there's no negative numbers from a square root.

Therefore, the right answer is the third choice.

If you want to define exactly the domain of this function, you just have to solve the expression for

This means that must be equal or greater than 20 to define the function.

i have no clue at all sorry
