Answer:
<em>Vertex: (3,4)</em>
Step-by-step explanation:
<u>Vertex form of the quadratic equation</u>
The vertex form of the quadratic function has the following equation:

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The parabola is given as:

Comparing with the equation:
a=2, Vertex: (3,4)
The graph of the parabola is shown in the image below
