{x|x∈R}
start set x such that x is in the real numbers end set
{x|x≥0}
start set x such that x is greater than or equal to 0 end set

{x|x>0}
start set x such that x is greater than 0 end set
[0, ∞)
[0, ∞)
(0, ∞)
{x|x≥0} and [0, ∞)
The correct representations for the domain of a function given by elevation (in feet) at or above sea level are:
1. {x|x≥0} which can be read as "the set of all x such that x is greater than or equal to 0". This represents all elevations at or above sea level.
2. [0, ∞) which can be read as "the interval from 0 to infinity, including 0". This represents all elevations at or above sea level, including sea level itself.
The other representations listed do not include the elevation at sea level itself.
The correct representations for the domain of a function given by elevation (in feet) at or above sea level are:
- {x | x ≥ 0}
- [0, ∞)
- (0, ∞)
