Question

Please help??
f(x) = √ (x+8) - x - 1 ; f(√ (2)+1) = ?

Answer 1

\[f(\sqrt{3}) =(\sqrt{(3)}+8)-(\sqrt{3})-1 \] I think this is supposed to be your setup.

Answer 2

\[f(\sqrt{2}+1) =((\sqrt{(2)}+1)+8)-(\sqrt{2}+1)-1\]
or perhaps this

Answer 3

I think I tried that. None of my answers are coming out right though.
