Now because the inverse of the mapping $x \mapsto 2x$ is $x \mapsto \frac$, then scaling $y$ coordinates by $A$, then shifting up by $D$ makes sense. On the other hand say we perform $x \mapsto 2x$, now we have $y-f(2x)=0$. Reflections A vertical reflection is a reflection across the x x A horizontal reflection is a reflection across the y y The reflected equation, as reflected.
