If you're referring to a quadratic equation or a parabola, the vertex is indeed a crucial point. The vertex form of a quadratic function is generally written as:

$y = a(x-h)^2 + k$

In this form, $(h, k)$ represents the vertex of the parabola. If you believe the vertex is at $(2, 1)$, that would suggest the equation is in the form:

$y = a(x - 2)^2 + 1$

Here, $h = 2$ and $k = 1$, so the vertex is located at $(2, 1)$.

If you have a different equation or specific values that need checking, please provide them, and I can confirm or adjust this based on the given function.

Would you like further clarification or more details?
