Consider the universal set $\mathbb{R},$ define the interval $A = [-8,1],$ interval $B = (-1,4),$ and $C$ be the negative real numbers. Complete the following exercises in interval notation.

---

1. $A \cup B =$

2. $A \cap B \cap C =$

3. $A \cap (B \cup C) =$

4. $A^c\cup B^c \cup C^c =$

5. $(C-A)\cup(B-C) =$
