\n" ); document.write( "Write the equation of a parabola, in standard form, that goes through these points:
\n" ); document.write( "(0, 3) (1, 4) (-1, -6)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Graph the parabola above. Indicate the vertex and axis of symmetry.
\n" ); document.write( "

\n" ); document.write( "Standard form of the quadratic equation: \"f%28x%29+=+-+4x%5E2+%2B+5x+%2B+3\"
\n" ); document.write( "Axis of symmetry is at: \"x+=+-+b%2F2a\", or \"x+=+-+5%2F%282%28-+4%29%29\", or \"x+=+%28-+5%29%2F-+8\", or \"x+=+5%2F8\"
\n" ); document.write( "Substitute this value into the equation, and solve for k: the y-coordinate of the vertex. You will then
\n" ); document.write( "have the coordinates of the vertex, or (h, k). This should help you to graph the parabola. \n" ); document.write( "
\n" );
