Answer:

C is correct
Explanation:
In the given graph function break at point x=2.
Left side about point x=2 is parabolic and right side straight line.
So, it would be piece wise function.
For parabola:
vertex: (0,4) and passing point (2,8)



For x<2
For straight line:
Twp points (4,0) and (2,2)



For x≥2
Hence, The piece wise function will be
