The characteristics of the graph are:
The complete question requires that, we list the features of the graph (see attachment)
From the attached graph, we have the following observations
When the slopes on a graph are additive inverse, then the graph is a linear absolute graph
The maximum point on the graph represents its absolute maximum
The interval at which it increases and decreases means that the behavior of the graph is that; it increases, then decreases
Lastly, the time represent continuous values;
Hence, the graph is continuous
