Answer:
(0,16) or just 0 horizontally
Step-by-step explanation:
The x intercepts would be found by first setting these equations to equal zero!
[tex]x-4=0\\x+4=0[/tex]
Now we can add/subtract to solve for the zeros of the function!
[tex]x+4=0\\-4\\x=-4\\\\x-4=0\\+4\\x=4[/tex]
The mid-point between 4 and negative 4 is 0, so the vertex is at (4,-16)!
