The given quadratic function is in vertex form, which is \( y = a(x-h)^2 + k \), where \((h, k)\) represents the vertex of the parabola.
In your equation:
\[ y = -10(x + 15)^2 - 18 \]
Here, we can identify:
- \( h = -15 \) (since \( x + 15 \) means \( h = -15 \))
- \( k = -18 \)
Therefore, the vertex of the parabola is:
\[ (-15, -18) \]
