Figure 7 shows the curves with equations
$$\begin{aligned}
& y = k x ^ { 2 } \quad x \geqslant 0
& y = \sqrt { k x } \quad x \geqslant 0
\end{aligned}$$
where \(k\) is a positive constant.
The finite region \(R\), shown shaded in Figure 7, is bounded by the two curves.
Show that, for all values of \(k\), the area of \(R\) is \(\frac { 1 } { 3 }\)
