The equation of a circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

Substitute the given values into the equation:

(x - (-3))^2 + (y - (-4))^2 = 3^2

Simplify:

(x + 3)^2 + (y + 4)^2 = 9

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
