    they all start the same right? with \(-4(x-3)^2\)?

    then replace \(x\) by \(3\) in the original equation and see what you get for \(y\)

    if that is what you got, then \[y=-4x^2+24x-29\] is the same as \[y=-4(x-3)^2+7\]

    so max height is 7 when \(x=3\) it must be right, too much of a coincidence otherwise if you had gotten -18 then we would know something was wrong

    x2 + bx + (b/2)^2 = (x+b/2)^2 "Complete the Square" I think it should be 4. It's been a long time since I did that though so wait for someone else to check
