A)(f of g)(x)and the domain of f of g

B) (g of f)(x) and the domain of g of f

C) (f of h)(x) and the domain of f of h

please show work

**Reiny**, Wednesday, September 5, 2012 at 10:58pmI will do B), you do the others the same way ...

b)

(g of f)(x) to me means g(f(x))

= g(lnx)

= e^(3lnx)

since we can only take logs of positive numbers,

domain: x > 0

range: I hope you are familiar with the basic exponential function, so y>0
