Question 218435
if f(x)=3x-5 and g(x)=x-9 which expression is equivalent to (fog)(x)
 first thing make sure you can read it (fog)(x) is read as f of g of x or (f(g(x))  to sollve you will complete it like any other function and subtitute

(f(g(x))= 3(x-9)-5
        =3x-27-5
        = 3x-32

to check it plug a number in and check to make sure it works for both
