Given f(x) and g(x),   (f º g)(x) = f(g(x)) 
 
with f(x) = 4/x2   and g(x) = 3-2x,  First apply g, then apply f to that result as follows:
 
g(x) = 3x-2
 
f(g(x)) =  4/ (3 - 2x)2  = 4/ ((3-2x)(3-2x))

f(g(x)) = 4/ (4x2-12x+9)

          




























































































































 
f(x)= 4/x2 and g(x) = 3-2x
 
f(g(x)) = 4/ (3 - 2x)2
 
f(g(x)) = 4/(4x2 - 12x + 9)
