Work Step by Step
Use the table on page 62 (Translations and Reflections)
----------
If $f(x)=\sqrt{x}$, with whose graph we are familiar,
then $y=\sqrt{-x+2}-4=\sqrt{-(x-2)}-4=f[-(x-2)]-4,$
whose graph is obtained by
1. reflecting the graph of f(x) about the y axis,
then,
2. translating right by 2 units,
and then
3. translating down by 4 units.
