The graph is/has A. order 2 rotational symmetry about the origin
B. odd
C. symmetric about the y-axis
D. neither even nor odd

c.symmetric about the y axis

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
