1 Answer Monzur R In order to find for any function f (x), we must apply the 'transformation' y = x In order to do that, we must define x in terms of y, ie, find f (y), then set y = x Let y = f (x) y = (x − 3)3 1 y − 1 = (x −3)3 x − 3 = 3√y − 1Solution for f (x)=x^31 equation Simplifying f (x) = x 3 1 Multiply f * x fx = x 3 1 Reorder the terms fx = 1 x 3 Solving fx = 1 x 3 Solving for variable 'f' Move all terms containing f to the left, all other terms to the right Divide each side by 'x' f = 1x 1 x 2 Simplifying f = 1x 1 x 2G(x) = tanh(2x) gives f(x) = (1 x4) 128x4 Not a polynomial, but at least a rational function g(x) = tanh(3 2x) gives f(x) = 1 x3 which is the answer given by juantheron For RHS to be a polynomial you have a0 = 1 or a0 ≠ 1 and ai = 0 for i > 0 (which contradicts an ≠ 0 )
