Step-by-Step Solution

To solve the problem, we follow these steps:

  • Step 1: Recognize the form of the equation. The equation is given as y=(x+7)2+15 y = (x+7)^2 + 15 , which is in vertex form.
  • Step 2: Identify the vertex from the equation. The vertex form of a parabola is y=(xh)2+k y = (x-h)^2 + k , where the vertex is (h,k)(h, k).
  • Step 3: Determine the values of hh and kk. Here, (x+7)(x+7) means that h=7h = -7 (notice the sign change), and the constant +15+15 is k=15k = 15.

By recognizing the form of the equation and substituting the values, the vertex of the parabola is (7,15)(-7, 15).

Answer

(7,15) (-7,15)
