Hey,

I just want to make sure I correctly understand unit vectors. I know they indicate units of length or magnitude, but how does that play out practically speaking? Take the following example.

xf(x)=x^21 1

2 4

3 9

4 16

And so on. In layman's terms, what is exactly going on there? It looks like a simple exponential expression, but is that correct? Probably not, because wouldn't you just write f(x)=x2 (squared)? I just don't quite get the whole concept...

What if it's f(x)=x^3? How does that play out?

Thanks in advance!
