Question

Carly is traveling to visit family. She drives x miles on the first day and y miles on the second day for a total of 800 miles. What are the domain and range of this relationship?

Answer 1

domain: 0 ≤ x ≤ 800

range: 0 ≤ y ≤ 800

Explanation:

Answer 2

The domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

Explanation:

We are given that Carly is traveling to visit family.

She drive distance on first day = x

She drive distance on second day = y

We are also given that Carly is travelling a total of 800 miles.

So,x+y=800

We are supposed to find domain and range of this relationship.

y=800-x

Domain : (-∞,∞)

Range:(-∞,∞)

Hence the domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.
