Inverse Variation
Captions available
The idea
Two quantities vary inversely when y = k/x — doubling one halves the other.
In practice
If y = 6 when x = 2, then k = 12; at x = 4 the value drops to 3, the product xy holding 12.
Where people slip
Inverse variation is a relationship, not Video 293's inverse function.
