Answer :
Hi!
This function is in [tex]y=a|x-h|+k[/tex] form.
The vertex is always (h, k).
Using the given equation, your vertex is (3, 6).
Now, you might be thinking, "If it's "x - 3", then why isn't the vertex (-3, 6) instead of (3, 6).
This is because, if you look at the absolute value function form, is says "x - h", which means the opposite of "h". Therefore, it really is (3, 6).
