If lateral magnification is negative what does that mean?

2. Relevant equations

m = -di/do

3. The attempt at a solution

From what I understand that focal distance for converging devices (concave mirrors and convex lens) is always positive. So this would make m="-" since di= "+". Also that a negative lateral magnification would mean less power. My question are:

1) Is the above correct?

2) If the object was within the focal point the image would be virtual and upright, what would happen to power then?

3) If I increase the focal distance would that mean I would decrease the power of the lens or mirror based on this formula: P=1/f?

4) Based on this formula: P=1/f = 1/di + 1/do, the farther the object is from the lens or mirror the greater power is?
