a) At its maximum or vertex. t=4.08163
\n" ); document.write( "b) 83.6327
\n" ); document.write( "c) It is the vertex- the highest point
\n" ); document.write( "vertex | (4.08163, 83.6327)
\n" ); document.write( "d) x = 8.21296
\n" ); document.write( "e) when y=0 ;when the parabola cross the x axis
\n" ); document.write( "set h(t)=0 and solve for x
\n" ); document.write( "f)when the parabola cross the x axis
\n" ); document.write( "g) set h(t)=0 and solve for x
\n" ); document.write( "
