OK, assume that the ground is the x-axis and the y-axis is the axis of symmetry.
\n" ); document.write( "Using the vertex form,
\n" ); document.write( "\"y=a%28x-0%29%5E2%2B4\"
\n" ); document.write( "When,
\n" ); document.write( "\"x=3.5\", then \"y=0\"
\n" ); document.write( "\"0=a%287%2F2-0%29%5E2%2B4\"
\n" ); document.write( "\"0=a%2849%2F4%29%2B4\"
\n" ); document.write( "\"a%2849%2F4%29=-4\"
\n" ); document.write( "\"a=-16%2F49\"
\n" ); document.write( "So then,
\n" ); document.write( "\"y=-%2816%2F49%29x%5E2%2B4\"
\n" ); document.write( ".
