Algebra.Com's Answer #109037 by oscargut(2103)![]() ![]() You can put this solution on YOUR website! f(x) = x ^2 + 2\r \n" ); document.write( "\n" ); document.write( "then -b/2a = -0/2=0 \n" ); document.write( "V=(0,f(0))=(0,2)\r \n" ); document.write( "\n" ); document.write( "Axis: x=0 \n" ); document.write( " |
