Variations and rational functions

Question

1. Explain the transformation of the graph above from the parent function, f(x) = 1/x. Make sure you include an explanation of your thought process. Check the graph carefully for a stretch or shrink as one of the transformations.

2. The force required to move an object by a lever and fulcrum varies inversely with the distance from the fulcrum that the force is applied. If the force required to move the rock at a distance of 9 feet is 80 lbs, what would be the force required with a distance of 15 feet? Make sure to explain your thought process.
