#1:

you will be applying offsets to the basic equation. If the graph is moved up 1 unit then y gets replaced by y -1. If it is moved down, then y gets replaced by y + 1

Why does it seem that the signs are wrong???--the way I think of it is that---when you put in a positive offset---the variable now needs to be smaller to get the same result.

Similar logic applies to the x axis.

For "stretch or shrink", study the shape of the function and any symmetry or NON-symmetry. In this case, there will be symmetry about the 45 degree line that goes through the origin. This is because y = 1/x is the same as x = 1/y
