Find the values of $x$ for which $y = [x(x – 2)]^2$ is an increasing function.

Question

$\begin{array}{1 1} (A)\;\text{f decreasing for 0< x< 1 and x> 2} \\(B)\;\text{f increasing for 0< x< 1 and x> 2} \\ (C)\;\text{f is neither increasing nor decreasing for 0 < x < 1 and x> 2} \\ (D)\;\text{Cannot be determined.} \end{array}$
