How do I find the symmetry for y=-x^2+6x-9
\n" ); document.write( "For quadratic equation written in standard form \"highlight%28y=ax%5E2%2Bbx%2Bc%29\", you can find the axis of symmetry with the formula \"highlight%28x=-b%2F2a%29\".
\n" ); document.write( "For this equation: a=-1, b=6 and c=-9
\n" ); document.write( "\"x=-%286%29%2F2%28-1%29\"
\n" ); document.write( "\"x=-6%2F-2\"
\n" ); document.write( "\"x=3\"
\n" ); document.write( "Happy Calculating!!!
