Answer:

B) y = x2 - 3

Explanation:

Suppose you have a function y = f(x), you can do these following operations on the function:

Shift up a units:
y = f(x) + a

Shift down a units:
y = f(x) - a

Shift left a units:
y = f(x + a)

Shift right a units:
y = f(x - a)

So the correct answer for this question is:

B) y = x2 - 3
