I need help with my week 6 math assignment.  The math question is attached.

 

 

In photography fixed focal length means that the focal length is not adjustable.
Photographers are unable to zoom in and out on a particular subject when using such a
lens. Not being able to easily zoom in on a subject might seem like a huge
disadvantage. But such lenses are credited with being able to produce much higher
quality pictures in controlled settings.
In order for a film camera with a fixed focal length F to focus on an object located a
distance x from the lens, the film must be placed a distance y behind the lens. F, y, and
x are related as follows Now suppose a camera has a lens with focal length F = 65.
1. Explain what happens to the focusing distance y as the object moves far away
from the lens.
2.
Explain what happens to the focusing distance y as the object moves closer and
closer to the lens.
3.
In general, why is it not possible to cross a vertical asymptote?
