Solution

Problem 2 :

 a. f'(17) b. f'(24.5)

Solution

Problem 3 :

 a. f'(1.5) b. f'(11)

Solution

Problem 4 :

 a. f'(47.5) b.  f'(9)

Solution

Problem 5 :

 a. f'(20) b. f'(82.5)

Solution

Problem 6 :

 a. f'(25.5) b. f'(13.5)

Solution

1) a) f'(8) = 47.5 visitors/hours

b)  f'(3.5) = 119 visitors/hours
