The given equation is in the vertex form of a parabola, which is \( y = a(x-h)^2 + k \), where \((h, k)\) represents the vertex of the parabola.
In this case, the equation is:
\[ y = 4(x - 25)^2 - 61 \]
From this, we can identify:
- \( h = 25 \)
- \( k = -61 \)
Thus, the vertex is:
\((h, k) = (25, -61)\).
The correct response is \((25, -61)\).
