True

Step-by-step explanation:

The weird upside down U thing is the intersection symbol.

The intersection of two sets is the set containing elements that both sets have.

The intersection of sets A and B is the set that has the elements you find in both A and B.

The intersection of sets A and B is {-10, 10}.
