**Problem Statement:**Use the Master Theorem to give a big-O estimate for the recurrence relation:\[ f(n) = 2f\left(\frac{n}{3}\right) + 4. \] **Explanation:**This is a typical divide-and-conquer recurrence relation of the form:\[ T(n) = aT\left(\frac{n}{b}\right) + f(n), \]where:- \( a = 2 \) is the number of recursive calls,- \( b = 3 \) is the factor by which the subproblem size is reduced,- \( f(n) = 4 \) is the cost of combining the results of the subproblems. **Master Theorem Application:**For the Master Theorem, compare \( f(n) = 4 \) with \( n^{\log_b a} = n^{\log_3 2} \). Calculate \( \log_3 2 \approx 0.631 \).- Since \( f(n) = 4 = \Theta(n^0) \), and \( n^{\log_b a} = n^{0.631} \), we have: \( f(n) \) is \( \Theta(n^c) \) where \( c = 0 \).- The Master Theorem states: \[ T(n) = \begin{cases} \Theta(n^{\log_b a}) & \text{if } f(n) = O(n^{\log_b a - \epsilon}) \text{, for some } \epsilon > 0 \\ \Theta(n^{\log_b a} \log n) & \text{if } f(n) = \Theta(n^{\log_b a}) \\ \Theta(f(n)) & \text{if } f(n) = \Omega(n^{\log_b a + \epsilon}) \text{, for some } \epsilon > 0 \end{cases} \]- Here, \( f(n) = \Theta(n^0) \) and \( n^{\log_b a} = \Theta(n^{0.631}) \).- Therefore, \( f(n) = O(n^{\log_b a - \epsilon}) \) implies \( \epsilon = 0.631 \).**Conclusion:**Using
