Answer:

             y = (x - 4)² - 4

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                      f(x) = a(x - h)² + k

the vertex is (4, -4)  ⇒   h = 4,  k = -4

so:

  f(x) = a(x - 4)² + (-4)

    f(x) = a(x - 4)² - 4

So the right answer is the first one.
