Learning Objective: To demonstrate that the student understands the definition of Big O. To demonstrate that the student knows how to use the definition of Big O to formally determine the asymptotic time complexity of a specific function. Instructions: This exercise is graded, so include your solution in your word processing document. Problem: Using the formal definition of Big O, prove mathematically that f(n) = 2.5n + 4 is O(n). Hint: you must determine values for C and n0 and a function g(n).
