Inverse Variation Models (HSC SSCE Mathematics Advanced): Flashcards

Decreases

$y = \frac{k}{x}$

Constant of proportionality (or constant of variation)

Hyperbola

$y = \frac{k}{x^n}$

Determines how quickly $y$ decreases as $x$ increases

Substitute known values of $x$ and $y$, then solve for $k$

$y = kx^n$

Intensity becomes one-quarter

Varies inversely with
