How well would zero, zero fit your proposed curve?
When I fitted the two points it used 0,0
The RMSE was 0. I think three points define an x^2 (only) so need more points to verify it's X^2, and not e.g. sum: X^n.
bc
p.s. gal./mi. = AX^2 + C; A=5.63E-6, and C= -8.12E-4 So not quite 0,0 [X is air speed MPH] So I take good suggestion from chuck britton:
Using added 0,0:
A=5.616E-6; C = -4.47E-4 and RMSE = 4.47E-4
The graph with fits is here:
