Daily Equation #16 - y = a*x^2 + b*x

This is Day 16 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210

Continuing the series of polynomials today, with y = a*x^2 + b*x. Looks a bit like the Nike swoosh.

Details:
- units are in mm
- Range(x) = -50 to 50
- a = 1/25*.65, b = 2*.35

As always, I'm going to continue to post one equation per day until get bored or people lose interest. If there's a particular equation you'd like to see, leave a comment an
