Which of the following statements are true for the given function? (Choose all that apply).

a. f(1) = 14 means Neal downloaded 1 song and has $14 left on his gift card.

b. f(2) = 15 means Neal downloaded 2 songs and has $15 left on his gift card.

c. You could represent Neal downloaded 12 songs and has $3 left on his gift card with f(12)=3.

d. f(15)=0 represents that Neal has $15 on his gift card before he downloads any songs.
