Set Theory And Geometry

To solve the given problem, we need to understand and process the sets , , and .

Define:

• Set .
• Set .
• Set .

Step 1: Identify points satisfying both conditions.

For points where or in set , the conditions are:

• If , then .
• If , then .

In set , the points satisfy , and we need to find intersections with the conditions above.

Step 2: Calculate intersection points in .

Possible boundary values are:

• For : and .
• For : and .

These points are inside set since , and similarly for others.

Step 3: Calculate .

• For : .
• For : .
• For : .
• For : .

Summing these values gives .

The correct answer is: 12
