Answer:
D)
Step-by-step explanation:
<u>Vertex Form of a Vertical Parabola:</u>
Vertex ->
Axis of Symmetry ->
Vertical Scale Factor ->
- To turn
into vertex form, we need to complete the square on the right side
- Therefore, if
, then
completes the square on the right side
- This becomes
- This means that our function in vertex form is
Therefore, the vertex of the graph is .
