In the context of the function \( f(x) = -16x^2 + 38x \), where \( x \) represents time in seconds and \( f(x) \) represents the height of the ball in feet, the origin (0,0) corresponds to:
- At 0 seconds, the height of the ball is 0 feet.
Therefore, the correct response is:
At 0 seconds, the ball is at a height of 0 feet.
