Answer:


Step-by-step explanation:
The function
is incorrect as its roots are imaginary
.
So, the correct function is

Differentiating with respect to
we get

Equating with zero

Double derivative of the function

So, the function is maximum at 
Maximum profit is

The maximum profit made by the company is 
The number of clients required to make the maximum profit is
.
For this case we have the following equation:

We find the intersections with the axes:
- Intersection with the x axis:
Making
we have:

Thus, the intersection with the x-axis is:
- Intersection with the y axis:
Making
we have:

Thus, the intersection with the y-axis is
Answer:
The intersection with the x axis is: 
The intersection with the y axis is:
