Sarina throws a ball up into the air, and it falls on the ground nearby. The ball's
height, in feet, is modeled by the function f(x) = -x2 - x + 3, where x represents time
in seconds. What's the height of the ball when Sarina throws it?
C
A) 4 feet
B) 2 feet
C C) 3 feet
D) 1 foot

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.

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
