Unit 1 Domain, Range, Functions

4. Madelyn is on a hiking trail that goes north to south. Her elevation, in feet, can be found using a function where x represents the miles she went north. Negative x values would find the elevation if Madelyn hiked south. Determine an appropriate domain for the function.
