Question
The elevation relative to sea level in the United States ranges from −282 feet in Death Valley, California to 20,320 feet on Mount McKinley, Alaska. Write the range of elevations in interval notation and in set-builder notation.

1. Tryphena
The intervals are given as follows:
• In range notation: [-282, 20,320].
• In set-builder notation: {x|x ∈ ℝ, -282 <= x <= 20,320}

### What is the range of elements notation for interval?

The range of elements notation for interval is given by:
[a,b].
In which:
• a is the smallest value.
• b is the greatest value.
In this problem these values are given by:
a = -282, b = 20,320.
Hence the interval in range notation is given by:
[-282, 20,320].

### How to write the interval in set-builder notation?

The same interval can be written as follows, using set-builder notation?
{x|x ∈ ℝ, a <= x <= b}
Hence, for the situation described in this problem, the set-builder notation for the values is:
{x|x ∈ ℝ, -282 <= x <= 20,320}
