Let f be the relation which takes as input a song title from the list, and which outputs the number of characters in the name of the album on which it appears (as listed on the table), excluding spaces. For example, f("Bad Guy") 32 characters (check this yourself). Similarly, f("Shape of You") = 1. 32 since the album title "When We All Fall Asleep, Where Do We Go?" has Is f a function? If so, is it one-to-one? Explain your answers. If it's one-to-one, explain in words (with some examples) what f-1 does.
