Answer:

Option C.

Step-by-step explanation:

It is given that the ball's height, in feet, is modeled by the function

f(x)=-x^2-x+3

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.

f(0)=-(0)^2-(0)+3

f(0)=0+0+3

f(0)=3

The height of the ball is 3 feet when Sarina throws it.

Therefore, the correct option is C.
