Answer:
(C) 3 feet
Step-by-step explanation:
We have a function of f(x) here. When Sarina throws the ball, it has been 0 seconds since she threw it.
Since x represents the amount of seconds, we can find the height of the ball (f(x)) by substituting x in as 0.

0 squared is 0, 0 minus zero is 0, and 0+3 = 3, so

Meaning that when Sarina threw the ball, it's height was 3 feet.
Hope this helped!
