A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce:

f(n) = 9(0.7)n

What does the number 0.7 represent?

The ball bounces to 30% of its previous height with each bounce

The height at which the ball bounces at the nth bounce is 0.3 feet

The ball bounces to 70% of its previous height with each bounce

The height from which the ball was dropped at the nth bounce is 0.7 feet
