We can notice that this is an inequality involving circles, since the equation of a circle is simply ( x − h ) 2 + ( y − k ) 2 = r 2 . Since ( x − 2 ) 2 + y 2 ≥ 2 , we know that the shaded region must be outside of the interior of the circle. The only letter that matches that diagram is B , so we're done.
