B. y=x²
y = -x² +18

C. y=x²
y = x² + 18

D. y=x²
y=-x²-x-18

Answer:

B

Step-by-step explanation:

We see the graph of y=x², so eliminate A.

Since the second graph opens downwards, the coefficient of x² must be negative, so eliminate C.

Also, the axis of symmetry is x = 0, so eliminate D.

This leaves us with B
