Suppose that the following 40-letter alphabet is used for all plaintexts and ciphertexts: a-z with numerical equivalents 0-25, blank-26, m27, ? -28, $-29, the numerals 0--9 with numerical equivalents 30- 39. suppose that plaintext message units are digraphs and ciphertext message units are trigraphs (i. e., k 2, 1 .. 3, 402

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
