Suppose that the functions \( u \) and \( w \) are defined as follows \[ \begin{array}{l}u(x)=-2 x-2 \\ w(x)=-x^{2} \\ \text { Find the following. } \\ \qquad(w \circ u)(4)=\square\end{array} \]

To find \((w \circ u)(4)\), we start by finding \(u(4)\) and then using that result to find \(w\) of the result. 1. Calculate \(u(4)\): \[ u(4) = -2(4) - 2 = -8 - 2 = -10 \] 2. Now, substitute \(-10\) into the function \(w\): \[ w(-10) = -(-10)^2 = -100 \] Therefore, \((w \circ u)(4) = -100\).
