Graphing Inverse Variation y = k x Graphs of inverse functions will look something like the cross between a linear graph and a parabolic curve. In this case, we are just looking at the graph in the first quadrant. When we look at a true inverse variation function, there will always be two graphs to the functions, diagonal from each other.

INVERSE VARIATION An equation of the form y=k x or xy=k k!0 is called inverse variation. In this situation, as the variable x increases, the variable y decreases and the reverse is also true. The graph is a curve that never touches either axis. Example The time it takes to travel a fixed distance varies inversely with the speed traveled. If it ...
