In cryptography, inverse functions are used by government agencies and other
businesses to encode and decode information. the alphabet is a = 1, b = 2, c = 3,
if the encoding function is y = 3x + 4 and the code numbers are 43, 7, 25, and
19, what is the encoded word? (find the y values of the inverse.)
