OK, not really. You know and I know there’s no such thing as a negative-dimensional vector space.
And yet…

Computational Tools
The best way, and often the only way, to learn new statistical procedures is by doing. We will therefore make extensive use of a flexible (open-source and free) statistical software program called R
and a companion package called Zelig.

I am not exactly sure of what I'm supposed to do in the following question:
Describe and correct the error, given the functions f(x)=3x - 5 and g(x)=1/3 - 4/3.
The first equation is as follows:
g(-3)= 1/3 - 4/3 (3)
