I have graphed this in 3 steps to try and show you pictorially how it is done.

https://www.desmos.com/calculator/aihasozfoa

Only y=x^3 is displayed first.

then click on the second circle to show y=-x^3

now  y=|x^3|   is a combination of theses because y must be positive.

If you now display y=|x^3| you will see that the graph looks a bit like  a concave up parabola.

You beat me Alan.  :(

Two answers are always better than one!  :))

Your answer is neat though Melody!  I didn't realise you could click on the circular icons in Desmos to switch the curves on and off.

Thanks Alan, that is a really neat feature in Desmos that I have only just started to make proper use of.
