1) . So what can you say about ?
2) and . So what can you say about ?
The questions is simplify:
(a) [6-2y] if y≥3
(b) [x+3] - [x-2] if -2<x<0.
So far i know that if x is greater than or equal to zero then x is positive. After that I don't know what to do. It gets confusing for me. Can someone explain in detail how to do this?
