Question

What is the domain of the function y= radical x?

Answer 1

Explanation:

Can you write this as y = √x?

The domain of the function y = √x is [0, ∞ ). In elementary algebra, before you encounter imaginary numbers, y = √x is not defined for negative x.

Answer 2

Answer:
`x\geq0` or
`[0,\infty)`

Explanation:

You have the function:

`y=√(x)`

The domain of the function is the set of all the possible input values that the function can has.

We know that the square root of a negative number is not defined in the Real numbers. Therefore, "x" cannot be a negative number.

Then the domain of f(x) will be:

`x\geq0` or
`[0,\infty)`
