The graph that would most likely be associated with the model is graph (a)
How to determine the graph?
From the question, we have the following highlights:
- Data points = 8 i.e. eight-year period
- Function type = quadratic function
A quadratic function follows a curved or parabolic path.
This means that it increases, then rests at a maximum and then decreases.
Graph (c) and (d) do not show the above highlight.
The graph (b) has 2 maximum points;
This means that the graph of Mr. Waller's company is graph (a)
