Hello, skipping the formal introduction, I came to seek help with math (duh).

This site was recommend to me by a good friend and now in need and 1:20 am I have no one to turn to for explanations so I though I would give this site a shot.

I have to extrapolate data from a given quadratic equation, however I am confused by one of the variables. (E)

So here it is, and my thanks in advance to anyone who can help me out.

y = 3E-18x3 - 6E-10x2 + 0.0316x - 76329
