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)=√(x^{2}+32)
(f@g)(7)=√(7^{2}+32)
(f@g)(7)=√(49+32)
(f@g)(7)=√81
(f@g)(7)=9
