Question 91956
I have three sets of ordered pairs:
(0,0) (432.57,0) (225, 190)
y=-0.0040682394x^2 + 1.759798301x
--------------------------------
(0,0) (40.16,0) (21,11)
y=-0.0273387017x^2 + 1.097922259x
--------------------------------

(0,0) (104,84,0) (58,64)
y=-0.0235578197x^2 + 2.46980182x
=========================== 

Each of these was generated by QuadReg on a TI-83 calculator.
