Domain and range of a linear function that models a real world
A construction crew is lengthening a road. Let L be the total length of the road (in miles). Let D be the number of days the crew has worked. Suppose that L=2D + 400 gives L as a function of D. The crew can work for at most 90 days.Identify the correct description of the values in both the domain and range of the function. […]
