Question 1057904
 Find the equation of the parabola for these three points
{{{ y = ax^2 + bx + c }}}

(1998,271.3), (2000,304.1), (2004,490.6)
----
Substitute the x/y values from each of those points
into the parabola formula.
----
That will give you 3 equations in a, b, c .
----
Solve the system for a, b, c.
----
Write the equation in x, y.
