1. Given the known information about the derivative of a function, and the function exists everywhere. Answer the following questions.
a) Identify the critical points of the function.
b) Create a first derivative sign chart.
c) Determine the intervals on which the function increases and decreases.
d) Classify the critical points as relative maximums, relative minimums or neither.
f'(1)=0 f'(3)=0 f'(8)=0

f'(x)<0 on (-∞,1), (3,8)

f'(x)>0 on (1,3), (8, ∞)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
