what is the maximum value of 8-2x-x^2
\n" ); document.write( "----------
\n" ); document.write( "f(x) = 8-2x-x^2
\n" ); document.write( "That's a parabola -x^2 - 2x + 8 in ax^2 + bx + c form
\n" ); document.write( "The max is the vertex at x = -b/2a
\n" ); document.write( "x = 2/-2 = -1
\n" ); document.write( "f(-1) = -1 +2 +8 = 9\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
