Hi, I'm having trouble with the problem h(x) = -16x^2 + 64x + 140 where h(x) equals the height. I'm trying to find the height, but I'm not sure how to. When asked to write the quadratic function in vertex form I came up with f(x) = 16(x+2)^2-56.\r

The height is represented by the y-coordinate of the VERTEX
\n" );
document.write( "The height, or y-coordinate of the VERTEX, or h(x) occurs at: \"x+=+-+b%2F2a\" -----> \"x+=+-+64%2F%282+%2A+-+16%29\" ------> \"x+=+%28-+64%29%2F%28-+32%29\" ------> x = 2
\n" );
document.write( "\"h%28x%29+=+-+16x%5E2+%2B+64x+%2B+140\" 
\n" );
document.write( "\"h%282%29+=+-+16%282%29%5E2+%2B+64%282%29+%2B+140\" ------- Substituting 2 for x
\n" );
document.write( "\"h%282%29+=+-+16%284%29+%2B+64%282%29+%2B+140\"
\n" );
document.write( "\"h%282%29+=+-+64+%2B+128+%2B+140\"
\n" );
document.write( "\"h%282%29+=+204\"
\n" );
document.write( "The height, or y-coordinate of the VERTEX occurs at h(2), and is:\"highlight_green%28204%29\"
\n" );
document.write( "It is that simple!
\n" );
document.write( "If you NEED to write the quad function in VERTEX form, then that's another story, but you don't have to! \n" );
document.write( "
