Which of the following is graphed below?

C is correct

Step-by-step 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

to complete this square you have to rotate about the origin 270 degrees clockwise.
