f(x)=-2x^2+2x+1
\n" ); document.write( ".
\n" ); document.write( "Axis of symmetry = -b/2a = -2/(2*(-2)) = -2/-4 = 1/2
\n" ); document.write( "Therefore, the equation of the line of symmetry is:
\n" ); document.write( "x = 1/2
\n" ); document.write( ".
\n" ); document.write( "Plug above back into:
\n" ); document.write( "f(x)=-2x^2+2x+1
\n" ); document.write( "f(1/2)=-2(1/2)^2+2(1/2)+1
\n" ); document.write( "f(1/2)=-2(1/4)+1+1
\n" ); document.write( "f(1/2)=-(1/2)+2
\n" ); document.write( "f(1/2)=-(1/2)+(4/2)
\n" ); document.write( "f(1/2)= 3/2
\n" ); document.write( ".
\n" ); document.write( "the x coordinate of the vertex is? 1/2
\n" ); document.write( "The y coordinate of the vertex is? 3/2
\n" ); document.write( "the equation of the line of symmetry is? x= 1/2
\n" ); document.write( "the MAXIMUM of the f(x) is (simplified fraction)? 3/2 \n" ); document.write( "
\n" );
