What is the domain of the function y = StartRoot x EndRoot?
Negative infinity less-than x less-than infinity
0 less-than x less-than infinity
0 less-than-or-equal-to x less-than infinity
1 less-than-or-equal-to x less-than infinity

  0 less-than-or-equal-to x less-than infinity

Step-by-step explanation:

The square root function, y=√x, is defined for non-negative numbers. Its domain is ...

  0 ≤ x < ∞
