Domain: 1) f(0) = 8 2) f(3) = 3) g(-2) = -2 4) g(2) = 0 5) f(g(0)) = f(2) =0 6) f(g(-2)) = f(-2) =undefined 7) f(g(2)) = f(0) =8 8) f(g(-1)) = f(1) =3

2
Domain: 9) g(f(3)) = g(-1) =1 10) g(f(2)) = g(0) =2 11) g(f(1)) = g(3) =1 12) g(f(0)) = g(8) =undefined 13) f(f(4)) = 8 14) g(g(0)) = g(2) =0f(0) =

3
Domain: 15) g(f((g(4)))= g(f(4)) =2g(0)) = 16) When is f(g(x)) = 8 On the graph of f(x) what x value gives us 8 ? So g(x) = 0On the graph of g(x) what x value gives us 0 ? x = 2 x also equals some number between -2 and -1

4
Domain: 17) When is g(f(x)) = 4 So f(x) = 4 x = about.8 19) Is it possible for g(f(x)) = -3 ?18) Is it possible for f(g(x)) = -1 ?
