Algebra.Com's Answer #764375 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! I know bc it is negative -5x^2 it opens downward, so it is a maximum value. I thinking that part is right??? \n" ); document.write( "================= \n" ); document.write( "y = -5x^2 does have a maximum. \n" ); document.write( "------- \n" ); document.write( "I'm confused on how to find the value \n" ); document.write( "I could really use some help. \r \n" ); document.write( "\n" ); document.write( "I put in a & b into x= -b/ 2a \n" ); document.write( "The max is at x = -b/2a \n" ); document.write( "b = 0 \n" ); document.write( "---> max at x = 0 \n" ); document.write( "----> the point (0,0) is the max. \n" ); document.write( "=========================================== \n" ); document.write( "But I'm just not sure if that's what I'm supposed to use to get the answer \n" ); document.write( " |
