Answer:
Option C.
Step-by-step explanation:
It is given that the ball's height, in feet, is modeled by the function
where, x represents time in seconds.
We need to find the height of the ball when Sarina throws it. It means, we need to find the initial height of the ball.
Substitute x=0 in the given function, to find the initial height.
The height of the ball is 3 feet when Sarina throws it.
Therefore, the correct option is C.
