Algebra.Com's Answer #27226 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! Does the quadratic function y = -12(x+2)^2-7\r \n" ); document.write( "\n" ); document.write( " have it's vertex at (-2,7) \n" ); document.write( "X=-2 VALUE IS OK.BUT THEN WE GET Y=-7...SO VERTEX IS (-2,-7) \n" ); document.write( "SINCE Y=-7-12(X+2)^2...HAS ITS MAXIMUM WHEN X=-2,VERTEX REPRESENTS A MAXIMUM...THAT IS OPEN DOWN \n" ); document.write( " and open down?...OK \n" ); document.write( " If not,write a function that meets the criteria. \n" ); document.write( "Y=7-12(X+2)^2...HAS VERTEX AT (-2,7) AND OPENS DOWN WARDS. \n" ); document.write( " |
