Question

FindinA construction crew lengthened a road. It took 40 days. The graph shows the total length of the road (in kilometers) versus time (in days).Find the domain and the range of the function shown.

Answer 1

Domain = set of all possible x values

Domain = 0 ≤ x ≤ 40

We use less/greater and equal because 0 and 40 are part of the solution.

Range = set of all possible y values

Range = 60 ≤ x ≤ 180
