Inverse Variation Calculator
Solve inverse variation problems where y = k/x. Find the constant k, or solve for x or y given the inverse relationship.
y varies inversely as x: y = k/x (or xy = k). Enter any two values.
Enter two values to solve.
Inverse Variation Formula
y = k/x (equivalently, xy = k)
In inverse variation, as x increases, y decreases, and their product remains constant.
Example: y varies inversely as x. If y = 4 when x = 6, find y when x = 8.
k = xy = 6 × 4 = 24
y = 24/8 = 3
k = xy = 6 × 4 = 24
y = 24/8 = 3
FAQ
What does the graph of inverse variation look like?
A hyperbola. The curve approaches but never touches the x-axis and y-axis (asymptotes).
