We have, 2fx+ f1x= 4x +2x   ......1. Keeping x=1x, we get,    2f1x+fx=4x+2x ......2 Now, to find f(x), we need to solve above two equations. Multiplying equation 1. by 2 and subtracting with equation 2, we get, 3f(x) = .....

Here, f(x + 3) = x2 + 6x + 11.    Let, z = x + 3===> x = z - 3 So, f(z) = ( z - 3)2 + 6( z - 3) + 11              = z2 + 2        f(z) = z2 + 2 Replace z .....
