Question 722174: y=ax^2+bx+c
(0,29.8): 0a+0b+1=29.9
(2,29.9): 4a+2b+1=29.9
(4,30.1): 16a+4b+1=30.1
Find the values of a, b, and c such that y=ax^2+bx+c models this data. (Make into one equation).

You can put this solution on YOUR website!
Where did you get the "1" in each of your equations?
When you get the three equations in a, b, and c written correctly, solve the 3X3 system. Hint: Since the coefficients on a and b are zero in the first equation, you can determine the value of c directly and the system degenerates to a more easily solved 2X2 system.
