Convert to vertex form,
\n" ); document.write( " $\"f%28x%29=-2%28x%5E2-3x%29\"$
\n" ); document.write( " $\"f%28x%29=-2%28x%5E2-3x%2B%283%2F2%29%5E2%29%2B2%283%2F2%29%5E2\"$
\n" ); document.write( " $\"f%28x%29=-2%28x-3%2F2%29%5E2%2B9%2F2\"$
\n" ); document.write( "The max height occurs at the vertex at $\"t=3%2F2\"$ \r
