To solve for $f^{-1}(3)$, $f^{-1}(4)$, and $f^{-1}(5)$, we need to find the corresponding x-values on the graph where the function $f(x)$ equals the given y-values.

(a) $f^{-1}(3)$:

1. Look for $y = 3$ on the graph.
2. Follow horizontally to see where it intersects the function.
3. At $y = 3$, the graph intersects at $x = 2$.

Thus, $f^{-1}(3) = 2$.

(b) $f^{-1}(4)$:

1. Look for $y = 4$ on the graph.
2. Follow horizontally to see where it intersects the function.
3. At $y = 4$, the graph intersects at $x = 0$ and $x = 3$.

Thus, $f^{-1}(4) = 0$ and $x = 3$.

(c) $f^{-1}(5)$:

1. Look for $y = 5$ graphically). -( --- ; clearing..
