Answer
Since the graph of the function lies above its tangent line at each point of $(2,\infty)$.
So, concave upward on
$$
(2,\infty).
$$
Since the graph of the function lies below its tangent line at each point of $(-\infty, 2)$ .
So, concave downward on
$$
(-\infty, 2).
$$
Since a point where a graph changes concavity is $(2,3).$
So, Inflection point at
$$
(2,3).
$$
