Answer:
[tex]x\geq 0[/tex]
Step-by-step explanation:
Think about what the square root is actually doing: it's telling you what number multiplied by itself will reset in the value. For example, the square root of 25 is 5, since 5 * 5 = 25.
Think about the square root of a negative number. What number multiplied by itself will result in a negative number? There is none, since a negative number times itself will result in a positive number. Therefore, you can only take the square root of positive numbers. You can also take the square root of 0, since 0 * 0 = 0.
