Step-by-Step Solution

To solve this problem, we need to find the vertex of the given parabola y=(x7)27 y = (x-7)^2 - 7 . This equation is already in the vertex form of a parabola, y=a(xh)2+k y = a(x-h)^2 + k . In this form, the vertex is given by the point (h,k)(h, k).

Let's break it down:

  • The expression inside the parentheses, (x7) (x-7) , shows that h=7h = 7.
  • The constant term outside, which is 7-7, shows that k=7k = -7.

Therefore, the vertex of the parabola is given by the coordinates (h,k)(h, k).
Substituting h=7h = 7 and k=7k = -7 into the vertex form, we have:

Vertex: (7,7)(7, -7)

Therefore, the correct answer is choice 1: (7,7) (7, -7) .

Answer

(7,7) (7,-7)
