Answer 2

We have , f(x) = x2 - 3x + 2

We have , f(x) = x2 - 3x + 2f(f(x)) = f(x2 - 3x + 2)

We have , f(x) = x2 - 3x + 2f(f(x)) = f(x2 - 3x + 2)= (x2 - 3x + 2)2 -3(x2-3x+2)+2

We have , f(x) = x2 - 3x + 2f(f(x)) = f(x2 - 3x + 2)= (x2 - 3x + 2)2 -3(x2-3x+2)+2= x4 + 9x2 + 4 - 6x3 - 12x + 4x2 - 3x2 + 9x - 6 + 2

We have , f(x) = x2 - 3x + 2f(f(x)) = f(x2 - 3x + 2)= (x2 - 3x + 2)2 -3(x2-3x+2)+2= x4 + 9x2 + 4 - 6x3 - 12x + 4x2 - 3x2 + 9x - 6 + 2= x4 - 6x3 + 10x2 - 3x

We have , f(x) = x2 - 3x + 2f(f(x)) = f(x2 - 3x + 2)= (x2 - 3x + 2)2 -3(x2-3x+2)+2= x4 + 9x2 + 4 - 6x3 - 12x + 4x2 - 3x2 + 9x - 6 + 2= x4 - 6x3 + 10x2 - 3xf(f(x)) = x4 - 6x3 + 10x2 - 3x
