Final answer:
The graph of the quadratic function y = 2 + (x - 3)^2 is increasing over the interval (3, infinity) because it is a parabola that opens upwards with its vertex at (3, 2), and the function begins to increase to the right of this vertex.
Step-by-step explanation:
To determine over which interval the function y = 2 + (x - 3)^2 is increasing, we need to understand the behavior of a quadratic function. The given function is a parabola that opens upwards since the coefficient of x2 is positive. The vertex of this parabola is at (3, 2), which is also its minimum point.
Since a parabola opens upwards, the function is decreasing on the interval to the left of the vertex, and increasing on the interval to the right of the vertex. So, for x > 3, the function starts to increase, meaning the graph is increasing over the interval (3, infinity).
