Question

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, ∞)

(−∞, ∞ )

Answer 2

The correct representations for the domain of a function given by elevation (in feet) at or above sea level are:

1. {x|x≥0} - This represents all the values of x that are greater than or equal to 0. In the context of elevation, this means any elevation value at or above sea level (which is defined as 0 feet).

2. [0, ∞) - This indicates the interval from 0 to positive infinity, including both 0 and positive infinity. It represents the same idea as the previous representation: all elevation values at or above sea level.

Therefore, the correct answers would be:

- {x|x≥0}
- [0, ∞)

Answer 3

The correct representations for the domain of a function given by elevation at or above sea level are:

- {x|x≥0} (start set x such that x is greater than or equal to 0 end set)
- [0, ∞) (closed interval from 0 to infinity)
