Algebra.Com's Answer #654162 by FrankM(1040)![]() ![]() You can put this solution on YOUR website! it starts with y-k=a(x-h)^2\r \n" ); document.write( "\n" ); document.write( "so entering the vertex, we have\r \n" ); document.write( "\n" ); document.write( "y-2=a(x-3)^2\r \n" ); document.write( "\n" ); document.write( "this reduces the choices to A or B. \r \n" ); document.write( "\n" ); document.write( "With a vertex at (3,2) and its focus below it, at (3,0), the parabola opens downward, and the 'a' value must be negative. Choice A is the only possible solution. \n" ); document.write( " |
