# ExplanationTo solve this problem, we first need to understand what \(f^{-1}(x)\) and \(g^{-1}(x)\) mean. These are the inverse functions of \(f(x)\) and \(g(x)\), respectively. When we say \(f^{-1}(0)\), we are looking for the value of
such that \(f(x) = 0\). Similarly, \(g^{-1}(-18)\) means we are looking for the value of
such that \(g(x) = -18\).Looking at the table, we can see that \(f(5) = 0\), so \(f^{-1}(0) = 5\). Similarly, \(g(0) = -18\), so \(g^{-1}(-18) = 0\).# AnswerSubstituting these values into the original equation, we get:
