For this case we have to define function transformation:
Vertical translations:
Let
, to graph
, move the graph of
"a" upwards.
Horizontal translations:
Let
, to graph
, we must move the graph of
"b" units to the right.
If we have as initial function 
To obtain
we move the graph of
three units on the right.
To obtain
we move the graph of
six units up.
Thus, the vertex of
is located at: 
Answer:
The vertex of the graph of
is located at:
