IF the equation of the parabola is written y=ax^2+bx+c, then a must be.. \r\n" );
document.write( "The parabola on this graph is an upside down bowl with its vertex being at 2\r\n" );
document.write( "on the y axis... \r\n" );
document.write( "1. zero\r\n" );
document.write( "2. positive\r\n" );
document.write( "3. negative\r\n" );
document.write( "4. none of the above \r\n" );
document.write( "\r\n" );
document.write( "y = ax2 + bx + c\r\n" );
document.write( "\r\n" );
document.write( "is a right side up bowl if a is positive and an upside down bowl if a is negative.\r\n" );
document.write( "\r\n" );
document.write( "So the answer is 3.  The information given about the vertex is unnecessary.\r\n" );
