Transforming Functions

The green function is f(x) flipped horizontally so I understand the answer has to be a negative. g(x) is moved down once on the y axis so I understand the answer is a (-1/x) I just don't understand where the 2 comes from. It has to do with width on the x value. How do I figure out what the denominator should be based on the image above?

It's to do with height, not width, really. Like the description said, it was compressed vertically. Look at the y-coordinates of the vertices of -f(x) and g(x) (i.e. the values of -f(-2) and g(-2)), and note their relationship.
