Video solusi : Komposisi fungsi f dan g dirumuskan dengan (fo g)(x)=(4 x+5)/(8 x-1) ; x =/= (1)/(8) . Jika g(x)=2 x+1 , fungsi f(x) adalah...
a. f(x)=(2 x-3)/(4 x-5) ; x =/= (5)/(4)
b. f(x)=(-2 x+3)/(4 x+5) ; x =/=-(5)/(4)
c. f(x)=(2 x+3)/(4 x+5) ; x =/=-(5)/(4)
d. f(x)=(2 x+3)/(4 x-5) ; x =/= (5)/(4)
e. f(x)=(-2 x+3)/(4 x-5) ; x =/= (5)/(4)
