X+2=xx+y. I need to decide if it is an ellipse, parabola, hyperbola, or a circle. Once I decide I need to put into the right equation and be able to graph it.

\n" ); document.write( "Parabola:
\n" ); document.write( "y = -x^2+x+2
\n" ); document.write( "x^2-x = -y+2
\n" ); document.write( "x^2-x++(1/4) = -y+(9/4)
\n" ); document.write( "(x-(1/2))^2 = -(y-(9/4))
\n" ); document.write( "Vertex at ((1/2),(9/4))

\n" ); document.write( "p = -1/4
