The distance traveled, in miles, as a function of time, in hours, is defined by D(t). D(t) = Which times and distances are represented by the function? Check all that apply. The starting distance, at 0 hours, is 300 miles. By 2 hours, the distance traveled is 725 miles. At 2.5 hours, the distance traveled is 875 miles. At 3 hours, the distance is constant, at 880 miles. The total distance traveled in 6 hours is 1,062.5 miles.

Answer:
*The complete question is attached in image form with this answer*
The correct options are: (b) By 2 hours, the distance traveled is 725 miles. (d)At 3 hours, the distance is constant, at 880 miles. (e)The total distance traveled in 6 hours is 1,062.5 miles.
Explanation: At t = 2 hours, the answer would be:
D(2) = 300(2) + 125 = 725 miles (at t lies in the range of 0 and 2.5) <-- (Option b).
At t = 3 hours, the answer would be: D(3) = 880 (since t is in the range of 2.5 and 3.5) <-- Option (d)
At t = 6 hours the answer would become: D(6) = 75(6) + 612.5 = 1,062.5 miles (since t is in the range of 3.5 and 6) <-- Option (e). At t=0, D(0) = 300(0) + 125 = 125 ≠ 300 (since t lies in 0 and 2.5). At t=2.5, D(2.5) = 880 ≠ 875 (since t lies in 2.5 and 3.5)
