Question

The elevation relative to sea level of a parcel of land on an island in Florida ranges from 5 feet to 7 feet. Write the range of elevations in interval notation and in set-builder notation.

Answer 1

It is given that the elevation relative to sea level of a parcel of land on an island in Florida ranges from 5 feet to 7 feet.

Now, the range of elevations in the interval notation can be written as: [5,7]

Likewise, the range of elevations in the set builder notation can be written as: $\left \{ x|5\leq x\leq 7 \right \}$
