Question

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

Answer 1

Answer:

Step-by-step 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 $[0,\infty)$

Step-by-step explanation:

You have the function:

$y=\sqrt{x}$

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 $[0,\infty)$
