This is a parabola that opens upward, and the vertex (minimum point) will be at \"x=%28-b%29%2F%282a%29\". In this case, vertex is at \"x=+%288%29%2F%282%29=4\".\r

\n" ); document.write( "\n" ); document.write( "If x = 4, then y = 4^2 - 8*4 +22 = 16 - 32 +22=6. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I get a vertex of (4, 6) . Check it out with the graph:\r
