Transform the function into vertex form, and match the values.

Explanation:

The vertex form is: y = a(x-h)^2 + k, where (h,k) is the location of the vertex.

To convert the original equation into this form, we can divide both sides of the equation by 3: y = (2/3)(x-7)^2 - 5/3

Reading from this equation we can see that h = 7 and k = -5/3, and therefore the vertex is located at (7,-5/3).
