Solve the problem.The linear function f computes the distance y in miles between a car and the city of Quebec after x hours, where 
The graphs of f and the horizontal lines 
and 
are shown in the figure. (i) Is the car moving toward or away from Quebec? (ii) Determine the times when the car is 135 miles and 270 miles from Quebec.
