\n" ); document.write( "Using the vertex form of a parabola, \"y=a%28x-h%29%5E2+%2Bk\" where(h,k) is the vertex
\n" ); document.write( "f(x)= -2x^2+2x+3
\n" ); document.write( "f(x)=-2[x^2-x]+3
\n" ); document.write( "f(x)=-2[(x-.5)^2 - .25] +3
\n" ); document.write( "f(x)=-2[(x-.5)^2 +.5 +3
\n" ); document.write( "f(x)=-2[(x-.5)^2 + 3.5 V(.5,3.5), Line of symmetry x = .5
\n" ); document.write( " a = -2 < 0, parabola opens downward, vertex a maxixmum Pt F(x) = 3.5
