Answer:
option (2) is correct.
The vertex is (3 , -7)
Step-by-step explanation:
Given: the function
written in vertex form is
We have to write the vertex form of g(x).
For a given quadratic function
, we can rewrite it in vertex form
, where (h , k) represents the vertex of the function f(x).
For the given quadratic function
written in vertex form is 
On comparing , we get
h = 3 and k = -7
Thus, the vertex is (3 , -7)
Thus, option (2) is correct.
