Interval Notation
1. **State the problem:** Write the intervals describing the given inequalities using interval notation.
2. **For i) $x \succ 3$: **This means all real numbers greater than 3, not including 3 itself.
Interval notation is $$ (3, \infty) $$.
3. **For ii) $-7 < x < -2$: **This means $x$ is greater than $-7$ and less than $-2$, excluding both endpoints.
Interval notation is $$ (-7, -2) $$.
4. **For iii) $x$ is greater than $-3$ and less than or equal to $4$: **This means $x$ is in the range $$-3 < x \leq 4$$.
Interval notation is $$ (-3, 4] $$.
Therefore, the interval notations are:
- i) $ (3, \infty) $
- ii) $ (-7, -2) $
- iii) $ (-3, 4] $
