. The domain is the set of all real numbers, except x ≠ 0,x ≠ -2.
f(g(x))=f(x+8)=(x+8)3 g(f(x))=g(x3)=x3+8 They are never equal.
- The graph of f(g(x)) is the graph of f(x), shifted 8 units to the left.
The domain of f+g is . The range is y ≤ 3.25. (g/f) has the domain of all real numbers except x=0. The range is all real numbers.
f(g(x))= (dx+a)/(bdx+c). The domain of the function is all real numbers except x = (-c)/bd.
