### Technical Question: **Which of the following best characterizes the statements** A) \( f(x) = x^2 + x \lg^2 x \) is \( O(x^3) \) B) \( f(x) = x \lg x^x \) is \( \Omega(x^2 \lg x) \) #### Options: A. Only A is TRUE B. Only B is TRUE C. Both A and B are TRUE D. Both A and B are FALSE --- #### Explanation of Big O and Big Omega Notation: - **Big O Notation \(O(g(x))\)**: Describes an upper bound on the time complexity of an algorithm, representing the worst-case scenario. For example, \( f(x) = O(x^3) \) implies that \( f(x) \) grows at most as fast as \( x^3 \) for large values of \( x \). - **Big Omega Notation \( \Omega(g(x))\)**: Describes a lower bound on the time complexity of an algorithm, representing the best-case scenario or minimum time needed. For example, \( f(x) = \Omega(x^2 \lg x) \) implies that \( f(x) \) grows at least as fast as \( x^2 \lg x \) for large values of \( x \). This problem involves analyzing the given functions and their asymptotic behaviors to determine which statements about their time complexities are accurate.
