Answer to Problem 50RE
The formula that describes the cab charges is
Explanation of Solution
Given information:The given cab charges for first mile is
Calculation:
The function that can be used to describe the cab charges $3.20 for a mile and $1.35 for each additional mile is:
As the given interval is
The function that describes the fare is,
The cab charges for first mile is
Therefore, the formula that describes the cab charges is
(b)
To graph:The function in part (a) and write the values for which the function is discontinuous.
(b)
