Answer:

C. The apple is originally 8 ft above the ground

Explanation:

y is the height in feet at time x in seconds.

The y-intercept is the height in feet when x = 0 seconds. A y-intercept of 8 means the apple was 8 feet above the ground at 0 seconds, which we understand to be before any tossing takes place.

The y-intercept means the apple is originally 8 feet above the ground.
