On the test I was asked to calculate the area of a region bounded by:

$\displaystyle x=0$

$\displaystyle y=0$

$\displaystyle x=1$

$\displaystyle y={1 \over \sqrt[3]{x^2}}$

What's the easiest way to draw the latest line on the graph? Surely, at home I can use calculator to calculate y for x'es, or even Wolfram Alpha to do whole work for me, but during tests we are not allowed to use any of them.
