Find the standard form of the equation of the parabola with the given characteristic and vertex at the origin.
\n" ); document.write( "a. y^2=-x
\n" ); document.write( "b. y^2=-4x
\n" ); document.write( "c. x^2=-4y
\n" ); document.write( "d. x^2=-y
\n" ); document.write( "e. x^2=y
\n" ); document.write( "**
\n" ); document.write( "standard form of a parabola: y=(x-h)^2+k, with (h,k) being the (x,y) coordinates of the vertex.
\n" ); document.write( "If the coordinates of the vertex are at the origin, (0,0), as given, they do not appear in the equation
\n" ); document.write( "which becomes y=x^2.
\n" ); document.write( "Therefore, e, is the correct answer
\n" ); document.write( "
\n" );
