Wendy initially has 6 hours of pop music and 3 hours of classical music in her collection. Every month onwards, the hours of pop music in her collection is 9% more than what she had the previous month. Her classical music does not change. Which function shows the total hours of music she will have in her collection after x months?
f(x) = 6(1.09)x + 3
f(x) = 3(1.09)x + 6
f(x) = 6(0.09)x + 3
f(x) = 3(0.09)x+ 6
