    This is tricky.

    In quadratic functions, left and right shifts seem opposite to their orientation on the xy plane.

    A positive value in parentheses denotes a shift to the left while a negative denotes a shift to the right.

    For instance, in this question, y = (x + 2) ^2 represents a shift to the left.

    The two options without the parentheses represent up and down shifts, but these are not backwards. y = x^2 + 2 is a shift up two units.

    Therefore, y = (x + 2) ^2 is your answer.
