Tell whether the quadratic function has a maximum value or minimum value. Then find the value and round to the nearest tenth.
\n" ); document.write( "y= -x^2 - 2x+5
\n" ); document.write( "---------
\n" ); document.write( "Quadratic with a=-1, b=-2, c=5
\n" ); document.write( "----
\n" ); document.write( "Max or Min occurs where x = -b/2a = 2/-2 = -1
\n" ); document.write( "f(-1) = -(-1)^2 -2*-1 + 5 = 1+2+5 = 8
\n" ); document.write( "Max at (-1,8)
\n" ); document.write( "----------------
\n" ); document.write( "Max because the coefficient of x^2 is negative
