Can I get help on part e?

**Part 3: Big-Oh? K.** **Suggested reading:** Sections 2.1 and 2.2 of *Algorithm Design*. Below are four pairs of functions, labeled \( f \) and \( g \). For each, determine constants \( a \) and \( n_0 \) such that for all \( n \geq n_0 \), \( a \cdot f(n) \geq g(n) \). Give a clear argument as to why your choice of \( n_0 \) and \( a \) satisfy the conditions. **a.** \( f(n) = 2n + 3 \), \( g(n) = 5n \) **b.** \( f(n) = 2n + 3 \), \( g(n) = 5n + \log(n) \) **c.** \( f(n) = n^{1/4} \), \( g(n) = \log(n) \) **d.** \( f(n) = n \), \( g(n) = (\log_2 n)^4 \) **e.** \( f(n) = n^3 \), \( g(n) = 6n + 1 \) *Hint: you may assume that for all \( x > 0 \), \( \log(x) < x \).*
