Question

Suppose the weekly marginal revenue function for selling x units of a product is given by the graph in the figure.

 MR= 36,000,000(500-2x) /(2x + 500)3 
 
 
(a) What is happening to the revenue at
x = 150?
a)The revenue is decreasing.
b)The revenue is increasing.
c)The revenue is changing from decreasing to increasing.
d)The revenue is changing from increasing to decreasing.

What is happening to the revenue at
x = 250?
a)The revenue is decreasing.
b)The revenue is increasing.
c)The revenue is changing from decreasing to increasing.
d)The revenue is changing from increasing to decreasing.

What is happening to the revenue at
x = 350?
The revenue is decreasing. OR
The revenue is increasing.   OR
  The revenue is changing from decreasing to increasing. OR
The revenue is changing from increasing to decreasing.

(b) Over what interval is revenue increasing? (Enter your answer using interval notation.)
