Select all representations for the domain of a function given by elevation (in feet) at or above sea level.(2 points) Responses {x|x≥0} start set x such that x is greater than or equal to 0 end set {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 0 end set [0, ∞) [0, ∞) (0, ∞) (0, ∞) (−∞, ∞ )

Answer 1

{ x | x ≥ 0 }

{ x | x ∈ R }

[0, ∞)

(−∞, ∞ )
