Algebra.Com's Answer #176293 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! If the equation is y=ax^2 +bx +c, then the vertex is always at the value where x=-b/(2a). After you find x, substitute this back into the original equation (or let the calcluator do it for you!!) to find y.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Dr. Robert J.
