1. **State the problem:** We are given a piecewise linear graph with points at (-5, -3), (-3, 1), (-1, 1), (1, 3), (3, 4), (4, 0), and (6, 2). We need to identify intervals where the function is increasing, decreasing, constant, and find relative and absolute maxima and minima.
2. **Recall definitions:**
- Increasing: function values rise as $x$ increases.
- Decreasing: function values fall as $x$ increases.
- Constant: function values stay the same as $x$ increases.
- Relative max: a point where the function value is higher than nearby points.
- Relative min: a point where the function value is lower than nearby points.
- Absolute max/min: highest/lowest function value over the entire domain.
3. **Analyze intervals between points:**
- From $x=-5$ to $x=-3$: $y$ goes from $-3$ to $1$ (increasing).
- From $x=-3$ to $x=-1$: $y$ stays at $1$ (constant).
- From $x=-1$ to $x=1$: $y$ goes from $1$ to $3$ (increasing).
- From $x=1$ to $x=3$: $y$ goes from $3$ to $4$ (increasing).
- From $x=3$ to $x=4$: $y$ goes from $4$ to $0$ (decreasing).
- From $x=4$ to $x=6$: $y$ goes from $0$ to $2$ (increasing).
4. **Identify relative maxima and minima:**
- Relative max at $x=3$ where $y=4$ (peak before decreasing).
- Relative min at $x=4$ where $y=0$ (lowest point before increasing).
5. **Identify absolute max and min:**
- Absolute max is $y=4$ at $x=3$.
- Absolute min is $y=-3$ at $x=-5$.
**Final answers:**
- Increasing: $(-5,-3)$, $(-1,1)$, $(1,3)$, $(4,6)$
- Decreasing: $(3,4)$
- Constant: $(-3,-1)$
- Relative max: $(3,4)$
- Relative min: $(4,0)$
- Absolute max: $(3,4)$
- Absolute min: $(-5,-3)$
