By analyzing the piecewise function, we conclude that the first graph is the correct one,
<h3>
Which of the following is the graph of the piecewise function?</h3>
The first part of the piecewise function is:
f(x) = √(-x - 2) for x ≤ -2
This parts ends at:
f(-2) = 0
With that, we can discard the last two graphs.
Now, the second part is a rational function with a negative coefficient.
Because of that sign, when x is positive, the function tends to negative infinite near in the asymptote, while when x is negative, the function tends to positive infinite in the asymptote.
Because of that, we conclude that the correct option is the first graph.

Answer : The correct option is, (A) 
Step-by-step explanation :
First we have to calculate the volume of cylinder.
Formula used:
Volume of cylinder = 
where,
r = radius = 3 cm
h = height = 18 cm (We are assuming that 3 solid spheres stacked to each other = 3 × diameter of each sphere = 3 × 2 × 3 = 18)
Volume of cylinder = 
Volume of cylinder = 
Now we have to calculate the volume of 3 solid spheres.
Formula used:
Volume of 3 spheres = 
Volume of 3 spheres = 
Volume of 3 spheres = 
Volume of 3 spheres = 
Now we have to calculate the amount of empty space within a cylinder.
Amount of empty space within a cylinder = Volume of cylinder - Volume of 3 spheres
Amount of empty space within a cylinder = 
Amount of empty space within a cylinder = 
Therefore, the amount of empty space within a cylinder is,
