1. An exposure change from an image with a proper exposure is normally expressed as a change that either halves or doubles the overall lighting from the original exposure. How does the book write this formula out?

Accurate, life-size (1:1) output.
A+1 image doubles the light of the original; a-1 image halves the light of the original
When closer than 3 feet, the ratio approaches 1/2 and 1/2. This is important when photographing fingerprints on curved surfaces. Following the rule in this case could mess you up.
As long as the light, reflected from a single point in space, enters the lens and remains a circle, rather than coming together at the sensor at a specific point, the image can be considered 'confused' and out of focus. It does not matter whether the light would have become a point in front of or after the sensor,. If a circle of light is formed on the sensor, the result is an out-of-focus image.
