So we can find the function rule by looking at the wording of the phrase. The output IS 8 LESS THAN the input. So I made those letters large because these words translates into a piece of the phrase. Remember that the word is mathematically speaking means =, and less than means the less than symbol, <. So let's write it out again but with those pieces substituted in for those words. So now the statement reads the output= 8< the input. Now we know what it means, but we don't know what the output or the input is, but that isn't what this question is asking, so now let's put in a variable instead of input and output. So make sure u put input= x, and output= y, it doesn't matter what letter it is as long as it's showing that the input/output really means this. So if we put that into the statement, it reads y=8
