A construction crew is lengthening a road. Let z be the total length of the road (in miles). Let ò be the number of days the crew has worked. Suppose that L=4D+400 gives & as a function of D. The crew can work for at most 60 days. Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.

A construction crew is lengthening a road. Let z be the total length of
the road (in miles). Let ò be the number of days the crew has worked.
Suppose that L=4D+400 gives & as a function of D. The crew can work for
at most 60 days.
Identify the correct description of the values in both the domain and
range of the function. Then, for each, choose the most appropriate set
