Solve the problem.The figure shows the cost of renting a car, f(x), as a function of distance driven, x, in miles, for distances not exceeding 70 miles. 
(i) Find
f(x).(ii) Find
f(x).(iii) What can you conclude about
f(x)? How is this shown by the
graph?(iv) What aspect of costs of renting a car causes the graph to jump vertically by the same amount at its discontinuities?
What will be an ideal response?
(i) 45
(ii) 49
(iii) 
f(x) does not exist; the graph shows a discontinuity at x = 60
(iv) The graph jumps at its discontinuities due to per-mile charges.
