The sets A and B are defined as follows. A={z|z8} (Greater than or equal to sign) I've already determined the intersection (U) is the 0 with the line through it because there's no relation/number satisfying (or however you call it). I'm stuck on the A n B now. Not sure.

Question

The sets A and B are defined as follows.
A={z|z<4}
B={z|z>8} (Greater than or equal to sign)

I've already determined the intersection (U) is the 0 with the line through it because there's no relation/number satisfying (or however you call it). I'm stuck on the A n B now. Not sure.

anonymous · Answer

Write A n B and A U B using interval notation.***
