1. **State the problem:** We are given the function $$y = -|x + 4| - 3$$ and asked to analyze its graph and key features.
2. **Recall the absolute value function:** The basic absolute value function is $$y = |x|$$, which forms a V shape with vertex at the origin (0,0).
3. **Transformations:**
- Inside the absolute value, $$x + 4$$ shifts the graph 4 units to the left.
- The negative sign outside the absolute value, $$- |x + 4|$$, reflects the graph across the x-axis, flipping it upside down.
- The $$-3$$ shifts the graph down by 3 units.
4. **Vertex:** The vertex of the graph is at the point where the expression inside the absolute value is zero, i.e., $$x + 4 = 0 \Rightarrow x = -4$$.
Substitute $$x = -4$$ into the function:
$$y = -| -4 + 4 | - 3 = -|0| - 3 = -0 - 3 = -3$$
So the vertex is at $$(-4, -3)$$.
5. **Shape and arms:** Since the graph is a reflection of the absolute value function, it forms an upside-down V shape with vertex at $$(-4, -3)$$.
- For $$x > -4$$, the function behaves as $$y = -(x + 4) - 3 = -x - 4 - 3 = -x - 7$$.
- For $$x < -4$$, the function behaves as $$y = -(-(x + 4)) - 3 = x + 4 - 3 = x + 1$$.
6. **Intercepts:**
- **y-intercept:** Set $$x = 0$$:
$$y = -|0 + 4| - 3 = -4 - 3 = -7$$
So the y-intercept is at $$(0, -7)$$.
- **x-intercepts:** Set $$y = 0$$:
$$0 = -|x + 4| - 3 \Rightarrow |x + 4| = -3$$
Since absolute value cannot be negative, there are no x-intercepts.
**Final answer:** The graph of $$y = -|x + 4| - 3$$ is an upside-down V with vertex at $$(-4, -3)$$, y-intercept at $$(0, -7)$$, and no x-intercepts.
