What the problems look like

A few statements from this skill. Answers, hints and worked solutions live in the practice session.

1. Warm-up

   The point $(-2, 9)$ lies on the graph of $y = f(x)$. Give the coordinates $(x, y)$ of the corresponding point on the graph of $y = 3f(x)$.

2. Warm-up

   The point $(2, 8)$ lies on the graph of $y = f(x)$. Give the coordinates $(x, y)$ of the corresponding point on the graph of $y = -4f(x)$.

3. Warm-up

   The point $(9, 2)$ lies on the graph of $y = f(x)$. Give the coordinates $(x, y)$ of the corresponding point on the graph of $y = -3f(x)$.
