Answer:

 \frac{3x + 2}{6x + 7}  \\

given \: that \\  \\ f(x) =  \frac{1}{3x + 2}  \\ \\  so \: that \\ we \: can \: compair \: f(x) =  f(f \: (x) \\ f \: \: (f(x) \: \\  \\  =  \frac{1}{3.f(x) + 2}  \\  =  \frac{1}{3. \frac{1}{3x + 2}  + 2}  \\  =  \frac{1}{ \frac{3 + (3x + 2).2}{3x + 2} }  \\  =  \frac{1}{ \frac{3 + 6x + 4}{3x + 2} }  \\  =  \frac{3x + 2}{6x + 7}

✨✨hope it helps✨✨


shivamnagpal2003: i want to know why we multiplied the denominator by 3?
avinash2201: because here the X. is f(x)
shivamnagpal2003: but frm where tye 3 came?
avinash2201: so f {f (x) } = 3x + 2 = 3 .f(x) + 2
avinash2201: your question is that 1/(3x +2 )
