To defend against optimistic TCP ACK attacks, it has been suggested to modify the TCP implementation so that data segments are randomly dropped by the server. Show how this modification allows one to detect an optimistic ACK attacker.

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)
