How do I find the maximum value of Y=x^2-4
\n" ); document.write( "-----------
\n" ); document.write( "That doesn't have a max. It has a minimum.
\n" ); document.write( "----
\n" ); document.write( "Find the vertex.
\n" ); document.write( "x of the vertex = -b/2a = 0/2
\n" ); document.write( "x = 0 --> y = -4
\n" ); document.write( "Minimum at (0,-4)
\n" ); document.write( "
\n" );
