The formula would be:
\n" ); document.write( " $\"+h%28t%29+=+-16t%5E2+%2B+96t+\"$
\n" ); document.write( "The maximum height is where:
\n" ); document.write( " $\"+t%5Bmax%5D+=+%28-b%29%2F%282a%29+\"$
\n" ); document.write( " $\"+t%5Bmax%5D+=+%28-96%29%2F%282%2A%28-16%29%29+\"$
\n" ); document.write( " $\"+t%5Bmax%5D+=+3+\"$
\n" ); document.write( "Plug this value of $\"+t+\"$ back into equation
\n" ); document.write( " $\"+h%283%29+=+-16%2A3%5E2+%2B+96%2A3+\"$
\n" ); document.write( " $\"+h%283%29+=+-144+%2B+288+\"$
\n" ); document.write( " $\"+h%283%29+=+144+\"$
\n" ); document.write( "The maximum height is 144 ft
\n" ); document.write( "Here's the plot of $\"h\"$ & $\"t\"$
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-1%2C+8%2C+-20%2C+200%2C+-16x%5E2+%2B+96x+%29+\"$ \n" ); document.write( "

\n" );
