Write down the range of $f$.

Write down $f(2)$;

Write down ${f^{ - 1}}(2)$.

On the grid, sketch the graph of ${f^{ - 1}}$.

Notes:     Award A1 for both end points within circles,

A1 for images of $(2,{\text{ }}3)$ and $(0,{\text{ }}2)$ within circles,

A1 for approximately correct reflection in $y = x$, concave up then concave down shape (do not accept line segments).
