Answer

Yes, the function is decreasing on the interval $(2, 5)$.

Work Step by Step

For a graph to be decreasing on the interval $(2, 5)$, its value must be decreasing on the entire interval from $x=2$ to $x=5$ Notice that the graph is falling from $x=2$ to $x=5$. This means that the function $f$ is decreasing on the interval $(2, 5)$.
