<u>Answer</u><u>:</u>

-1 is not in domain

0 and 2 both are in domain.

<u>Explanation</u><u>:</u>

The radical function must have the domain greater or equal to 0. Here is why.

If we substitute any negative numbers in the equation

y =  \sqrt{x}

Then we would get the Imaginary Number, meaning it doesn't exist in Real Number system. That's why <u>any negative real numbers cannot be part of the domain</u>.

But that's for y = square root of x. There are like 4 types of radical function but this one is for example.

The equation in the question is the same type as the example equation.
