Consider the following table. Let f be the relation which takes as input a song title from the list, and which outputs the number ofcharacters in the name of the album on which it appears (as listed on the table), excluding spaces.For example, f("Bad Guy") = 32 since the album title "When We All Fall Asleep, Where Do We Go?" has32 characters (check this yourself). Similarly, f("Shape of You") = 1.Is fa 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.Let g be the relation which takes as input an integer between l and 20 (inclusive), and outputs the nameof the song with that rank on the list.For example, g(10) = "Bad Guy", since the song “Bad Guy" appears 10th on the list.Is ga function? If it's a function, is it one-to-one? Explain your answers.If it's one-to-one, explain in words (with some examples) what g does.
