1. Choose the equation of the parabola with a vertex at the origin and a focus at (0, –3). \r
\n" ); document.write( "\n" ); document.write( "1: Y=-1/3X
\n" ); document.write( "2: Y=1/12X^2
\n" ); document.write( "3: Y=-1/3X^2
\n" ); document.write( "4: Y=-1/12X^2
\n" ); document.write( "----------------
\n" ); document.write( "It's 4, y = -x^2/12
\n" ); document.write( "
\n" ); document.write( "
