Math 1314 Lab Module 4 page 7 8.2. You intercepted the following message from Boris and Natasha. 25 19 19 30 41 17 15 26 27 41 15 28 18 41 18 29 41 34 22 19 41 27 15 34 22 You do not know the encoding or decoding function but from previous work with Boris and Natasha you know their encoding and decoding functions are always linear and have 1 as the coefficient of x. You also know this message consists of 6 words. Using the encoding system described above, a. How would you decode the message? Explain your strategy in complete sentences using proper grammar and correct spelling b. Identify the decoding function. c. What is the message?Math 1314 Lab Module 4 page 6 Cryptology Applications: 8.1. Suppose f(x) = 6x - 2 is the encoding function. a. Encode "Collin Cougars". [The answer will be numbers. Remember to include the space.] Code: b. Find the inverse of f(x). c. Using the inverse function you just found, decode the following encoded message. Write the letters above the numbers in the code. [The answer should be words. Put spaces where appropriate!] 16 88 70 70 28 40 28 160 4 70 40 28 10 106 4 160 52 112 160 76 148 160 34 4 130 88 106 52 118 28 160 112 124 10 58 28 16 118 d.
