Question

If g(x) = 2x + 1 and fog (x)=6x-2, find f(x).​

Answer 1

Answer:

Hello,

Step-by-step explanation:

$g(x)=2x+1\\(fog)(x)=f(g(x))=f(2x+1)=6x-2==3*(2x+1)\\\\f(2x+1)=3*(2x+1) \\or f(y)=3(y)\\or \boxed{f(x)=3x}$

Answer 2

Answer:

$g(x) = f(x) \\ 2x + 1 = 6x - 2 \\ 2x - 6x = - 2 - 1 \\ - 4x = - 3 \\ x = \frac{3}{4}$
