Hi again Keith;
f(x) =√¯¯x+32
I believe this is...
f(x)=√(x+32).........If not, please let me know.
I have never seen (f@g)(x).  The use of @ is unfamiliar to me.  I researched it and cannot find anything.  I will therefore guess.
(f@g)(7)=√(x2+32)
(f@g)(7)=√(72+32)
(f@g)(7)=√(49+32)
(f@g)(7)=√81
(f@g)(7)=9
