From the image you provided, it appears you are working on a multiple-choice question related to identifying the vertex of a parabola. The graph shows a parabola opening upwards, and the vertex is the lowest point on the graph.

Looking closely at the graph, the vertex seems to occur at the point $(3, -1)$. Therefore, the correct answer to the question "What is the vertex?" would be:

(3, -1)

Would you like more details on how to determine the vertex from a graph?

Here are five related questions:

1. How do you find the vertex from the equation of a parabola?
2. What is the axis of symmetry of a parabola?
3. How can you determine if a parabola opens upwards or downwards?
4. How does the vertex relate to the maximum or minimum point of a parabola?
5. Can the vertex be calculated from the standard quadratic form $ax^2 + bx + c$?

Tip: The vertex form of a parabola’s equation is $y = a(x - h)^2 + k$, where $(h, k)$ is the vertex.
