Function s of $2 y = f *(3x - 6) - 2$

Question

$2 y = f * (3x - 6) - 2$

Given this function, does it indicate a vertical expansion by 2, a horizontal expansion by 3, a translation right by 2 and a translation of 2 units down?

Answer 1

HINT

For $y=f(x)$

• vertical expansion of $k \to y=kf(x)$
• horizontal expansion of $k \to y=f(x/k)$
• right translation of $k \to y=f(x-k)$
• down translation of $k \to y=f(x)-k$
