Dilations (HSC SSCE Mathematics Advanced): Flashcards

Transformation that stretches or compresses a graph

$y = f\left(\frac{x}{k}\right)$

Graph stretches (becomes wider)

Graph compresses (becomes narrower)

$y = lf(x)$

Graph stretches (becomes taller)

Graph compresses (becomes flatter)

$y = kf\left(\frac{x}{k}\right)$

x-coordinates (y-coordinates remain unchanged)

y-coordinates (x-coordinates remain unchanged)
