Given the function $f(x)$ sketched below,

1. Sketch $f(-x)$.

   Hint (a):

   Give each of the $x$-values in your table the opposite sign and graph the new function.

2. Sketch $-f(x)$.

   Hint (b):

   Since $f(x) = y$, give each of the $y$-values in your original table the opposite sign. Then graph the new function.

3. Sketch $f(f(x))$.

   Hint (c):

   Add a third column to your original table labeled $f(f(x))$. Then, for example, $f(f(-3)) = f(1) = -1$.
