Using the intercept in graphing, find the vertex and intercept and aketch of S=-16t^2+64r
\n" ); document.write( "----------
\n" ); document.write( "You probably mean S = -16t^2 + 64t
\n" ); document.write( "Same as y = -16x^2 + 64x
\n" ); document.write( "----
\n" ); document.write( "At x = 0, y = 0
\n" ); document.write( "At y = 0, x = 0 and x = 4
\n" ); document.write( "That gives you only 2 points, not sufficient to define a parabola.
\n" ); document.write( "-------
\n" ); document.write( "You can make a table to generate additional points:
\n" ); document.write( "

\r\n" );
document.write( "  x	 y	\r\n" );
document.write( "-4.0	-512	\r\n" );
document.write( "-3.5	-420	\r\n" );
document.write( "-3.0	-336	\r\n" );
document.write( "-2.5	-260	\r\n" );
document.write( "-2.0	-192	\r\n" );
document.write( "-1.5	-132	\r\n" );
document.write( "-1.0	-80	\r\n" );
document.write( "-0.5	-36	\r\n" );
document.write( "0.0	0	\r\n" );
document.write( "0.5	28	\r\n" );
document.write( "1.0	48	\r\n" );
document.write( "1.5	60	\r\n" );
document.write( "2.0	64\r\n" );
document.write( "2.5	60\r\n" );
document.write( "3.0	48\r\n" );
document.write( "3.5	28\r\n" );
document.write( "4.0	0\r\n" );
