Mark the correct alternative in each of the following:

Let A = {x ϵ R: x ≤ 1} and f : A A given by f(x) = x(2 – x).Then, f–1(x) is


Given that A = {x ϵ R: x ≤ 1} and f : A A given by f(x) = x(2 – x).


y = f(x)


y = x(2 – x)


y = 2x – x2


y - 1 = 2x – x2 -1


y – 1 = - (x2 + 1 – 2x)


(x – 1)2 = 1 – y
