    S.H.M - Netwon's Law of Cooling - Inverse Functions

    answer to inverse function the answer to that last question is f(x) = x^2 + 2x which means y= x^2 + 2x Interchanging x with y,you get x = y^2 + 2y. and now make y the subject of the formula, using completing the squares therefore, x + 1 = y^2 + 2y +1 x + 1 = (y + 1)^2...
