How can we help?

I am working with f(x)=x^3 and f(x)=x^3-x. The original is f(x)=x^3. I don't know the second equation has changed the first equation graphically. I typed it into a calculator, so I know it kind of looks like ~ meaning it is more curved than regular x^3 but I need to know what is happening so I can duplicate these results.

So there are a few tricks and rules for simple function visualisation, however this becomes more complex the higher grade of function you get (x^3,x^4 etc.)

The easiest way to see what happens when changing functions like this is to plot both of them for a few values of x. Say for example you choose a range of -5<x<5 and plot both functions. This will give you the best understanding of what happens and changes when adapting your functions!
