The diagram shows the graph of \(y = \mathrm { f } ( x )\), where
$$\mathrm { f } ( x ) = 2 - x ^ { 2 } , \quad x \leqslant 0 .$$
- Evaluate \(\mathrm { ff } ( - 3 )\).
- Find an expression for \(\mathrm { f } ^ { - 1 } ( x )\).
- Sketch the graph of \(y = \mathrm { f } ^ { - 1 } ( x )\). Indicate the coordinates of the points where the graph meets the axes.
