The equation is in vertex form, $\"y=a%28x-h%29%5E2%2Bk\"$
\n" ); document.write( "The function max or min occurs at the vertex and equals k.
\n" ); document.write( "The max of min is determined by $\"a\"$ .
\n" ); document.write( "If $\"a%3E0\"$ , then $\"k\"$ is the minimum.
\n" ); document.write( "If $\"a%3C0\"$ , then $\"k\"$ is the maximum.
\n" ); document.write( "In this case, $\"a=-1\"$ , so
\n" ); document.write( " $\"k=-3\"$ is the function maximum.
