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 < ∞

Comment on the question

This shows up again and again in domain problems, so is worth remembering. The value under the radical cannot be negative (but it can be zero).

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
