If you're not sure what the graph looks like, then just plug in some numbers for x, (x=1, x=2, x=3) and then plot the points. Then just connect them with a smooth line.

I don't actually understand your notation. What are those square brackets and "I"s?

I think it's pretty straight forward, albeit bizarre notation. The brackets mean nothing, and the "I...I" are supposed to be absolute value bars "|...|".
