You can put this solution on YOUR website!
The vertex of f(x) = a|x-h| + k is (h,k)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In the case of f(x) = 2|x| + 4, which is really f(x) = 2|x-0| + 4, we see that h = 0 and k = 4\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the vertex is (0, 4)\r
\n" ); document.write( "
