The vertex of g(x) is the same as the vertex of f(x).
The vertex of g(x) is 4 units above the vertex of f(x).
The vertex of g(x) is 4 units to the left of the vertex of f(x).
The vertex of g(x) is 4 units below the vertex of f(x).
The vertex of g(x) is 4 units to the right of the vertex of f(x).

well, if we see the graph of x^2
the vertex is (0,0)
if we reflect it acrosss the x axis, teh vertex is still (0,0)
verteical strech doesn't change the vertex
vertex of g(x) is same as f(x)
