Find the equation of the parabola for these three points
\n" ); document.write( " $\"+y+=+ax%5E2+%2B+bx+%2B+c+\"$ \r
\n" ); document.write( "\n" ); document.write( "(1998,271.3), (2000,304.1), (2004,490.6)
\n" ); document.write( "----
\n" ); document.write( "Substitute the x/y values from each of those points
\n" ); document.write( "into the parabola formula.
\n" ); document.write( "----
\n" ); document.write( "That will give you 3 equations in a, b, c .
\n" ); document.write( "----
\n" ); document.write( "Solve the system for a, b, c.
\n" ); document.write( "----
\n" ); document.write( "Write the equation in x, y.
\n" ); document.write( "Cheers,
