Question 1153885: 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=3D+300 gives "L" as a function of "D".
The crew can work for at most 70 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.
Domain Description of Values
a.) length of road in miles
b.) number of days crew has worked
Set of Values
a.) all real numbers from 0-70
b.) all real numbers from 3-300
c.) all real numbers from 300-510
d.) {70, 71, 72, 73, ...}
e.) {0, 1, 2, 3, ..., 300}
f.) {3, 6, 9, 12, ...}

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=3D+300 gives "L" as a function of "D".
The crew can work for at most 70 days.
--------------------
Domain for values D are the whole(probably) numbers from 0 to 70.
The range are the numbers from  to  .
