The answer is -10 because if you want to find f(2), x must be -1. Then, we make all x's -1, and we get 1 - 4 - 7, so the answer is -10.
For the record, Post #4, signed by GA, is not by the real GA.
I estimate History is eleven (11) years of age. Though his writing skills equate to the practiced skills of a senior high school student in syntax, punctuation, and coherency, I seriously doubt History will understand your post beyond that of basic criticism. He lacks life experience and education in critical analysis of literature. However, in a few years he will have the skills, and he will recognize your complexifacation of disjointed and non sequitur metaphors as the bullshit that it is. (It really sucks!)
It may not even take a few years... It’s an easy first assignment.
Did you know that I am not even 11 years old? Also, Im just doing what I am suppose to do as an answerer. I think that you said that I am misleading, and that they are copying my work. Who in the world cares? They are just hurting themselves, not us. We might not get anything benificial, but I do this for fun.
