To find \((f \circ g)(-2)\), we first need to compute \(g(-2)\) and then plug that result into \(f(x)\).

  1. Calculate \(g(-2)\): \[ g(x) = -x^3 \] \[ g(-2) = -(-2)^3 = -(-8) = 8 \]

  2. Now, we need to calculate \(f(g(-2)) = f(8)\): \[ f(x) = x^2 - 6 \] \[ f(8) = 8^2 - 6 = 64 - 6 = 58 \]

Thus, \((f \circ g)(-2) = 58\).

The correct response is: \((f \circ g)(-2) = 58\)
