To identify the vertex of the quadratic function \( y = -10(x + 15)^2 - 18 \), we can use the vertex form of a quadratic equation, which is given by:
\[ y = a(x - h)^2 + k \]
where \((h, k)\) is the vertex of the parabola.
In the given equation:
\[ y = -10(x + 15)^2 - 18 \]
we can rewrite the equation to match the vertex form:
\[ y = -10(x - (-15))^2 - 18 \]
Here, we can identify:
- \( h = -15 \)
- \( k = -18 \)
Thus, the vertex of the parabola is \((-15, -18)\).
