Hi there,
\n" ); document.write( "With y = x^2 - 4x - 7
\n" ); document.write( "when x = 0
\n" ); document.write( "y = (0)^2 -4(0) - 7
\n" ); document.write( "y = -7
\n" ); document.write( "when x = -1
\n" ); document.write( "y = (-1)^2 -4(-1) - 7
\n" ); document.write( "y = -2
\n" ); document.write( "Hope this helps you :-)
\n" ); document.write( "
