Devon thinks her function machine is broken. She dropped in a number, but nothing has come out. "First I dropped in 16, and the output was 4. Then I dropped in 9 and the output was 3. But I just dropped in -4 and nothing is coming out." "Ah," Michael says, "I think your machine is working just fine." What do you think the function is? Does Devon have a broken function machine or has Michael figured something out? Justify your answer completely.
