The vertex is (3, -2).
When looking at a graph of a parabola, the vertex is the highest or lowest point of the parabola, depending on whether it opens up or down. Here, it opens up, so the vertex here is the lowest point.
So once you figure that out, you just have to look at what the point's coordinates are, and for this problem, the vertex is at (3, -2).
I hope this helped you, and if I was correct, I'd appreciate if you marked my answer as Brainliest :)
