Answer 1

Answer: Option (3)

Explanation:

Since the parabola has a vertical axis of symmetry, we can eliminate Options (1) and (4).

To see whether options (2) or option (3) is correct, we can substitute in
`x=-1` and see if we get y=3.

Doing this with option (2), we get y = -3, so it is wrong.

Doing this with option (3), we get y = 3, as required.

So, option (3) is correct.
