You can put this solution on YOUR website!
h(t) = -16t^2 + 12t
\n" ); document.write( "Use ^ (Shift 6) for exponents.
\n" ); document.write( "-------------
\n" ); document.write( "The max height is the vertex of the parabola.
\n" ); document.write( "The vertex is at t= -b/2a
\n" ); document.write( "Find t, then h(t)\r
