\n" ); document.write( "The function has zeros at 0 and 1, so the equation is of the form

\n" ); document.write( "\"y=a%28x-0%29%28x-1%29\" or \"y=a%28x%29%28x-1%29\"

\n" ); document.write( "Use the coordinates of the other given point to determine the constant a:

\n" ); document.write( "\"-20=a%285%29%285-1%29\"
\n" ); document.write( "\"-20=20a\"
\n" ); document.write( "\"a=-1\"

\n" ); document.write( "The equation of the parabola is

\n" ); document.write( "\"y=-1%28x%29%28x-1%29\"
\n" ); document.write( "\"y=-1%28x%5E2-x%29\"
\n" ); document.write( "\"y=-x%5E2%2Bx\"
