Find the coordinates of the vertex and the equation of the axis of symmetry of the graph of the eqution. y=6+4x-1/2 x squared
\n" ); document.write( "---------
\n" ); document.write( "Put the equation in vertex form:
\n" ); document.write( "-1/2 x^2 +4x = y-6
\n" ); document.write( "(-1/2)(x^2- 8x + 4^2) = y-6-(1/2)*16
\n" ); document.write( "(-1/2)(x-4)^2= y-14
\n" ); document.write( "Vertex at x=4,y=14
\n" ); document.write( "Axis of symmetry is x=4
\n" ); document.write( "-------------
