1 answer:
Answer:
The answers for your two question problem are:
a. He should charge $7 dollars
b. Maximum value : f(5) = 130
Minimum value : f(2) = -32
Step-by-step explanation:
First problem
*When he charges $9 , the numbers of customers are an average of 1000
This means the revenue is
1000*$9 = $9000
*When he charges $7 , the numbers of customers are an average of 1500
This means the revenue is
1500*$7 = $10500
Since
$10500 > $9000
The owner should charge $7, to attract more customers and get higher revenue.
Second problem
f(x) = 2x^3 − 24x
To easily solve this problem, we can graph the equation using a calculator or any plotting tool.
Please, see attached picture
The highest point of the graph, in the interval [-3,5] corresponds to
f(5) = 130
and the lowest point :
f(2) = -32
