Which of the following equations is of a parabola with a vertex at (0, -3)?
y = (x - 3)^2
y = (x + 3)^2
y = x^2 - 3
y = x^2 + 3

Third option is correct.

Step-by-step explanation:

Since we have given that

We need a parabola with a vertex at (0,-3)

If we select the equation:

When we put x = 0, we get

And similarly, when we put y = -3, we get

Hence, third option is correct.
