1. **State the problem:** We need to analyze the function $f(x) = -(x + 1)^2 + 2$ and identify its graph, vertex, and axis of symmetry.
2. **Recall the vertex form of a quadratic function:**
$$f(x) = a(x - h)^2 + k$$
where $(h, k)$ is the vertex and $a$ determines the direction of the parabola (up if $a > 0$, down if $a < 0$).
3. **Identify the vertex and direction:**
Given $f(x) = -(x + 1)^2 + 2$, rewrite as $f(x) = -(x - (-1))^2 + 2$.
- Vertex is at $(-1, 2)$.
- Since $a = -1 < 0$, the parabola opens downward.
4. **Axis of symmetry:**
The axis of symmetry is the vertical line through the vertex, so:
$$x = -1$$
5. **Match with given graphs:**
- Graph C is a parabola opening downward with vertex at $(-1, 2)$.
- This matches our function exactly.
**Final answers:**
- The graph of $f(x)$ is Graph C.
- The vertex is $(-1, 2)$.
- The axis of symmetry is $x = -1$.
