Final answer:
The end behavior of the graph showing the production of bags over time at a constant rate is that, as the number of hours increases, the total number of bags produced also increases indefinitely.
Step-by-step explanation:
The question involves understanding the end behavior of a graph that represents the production of bags over time. Given the context that the machines produce bags at a rate of 50 bags per hour and there is no mention of a maximum production limit, the graph representing the total number of bags produced over time will be a linear function. Therefore, the end behavior of the graph will be:
a) As x increases, f(x) increases indefinitely.
This is because for each additional hour of machine work, 50 more bags are produced, and this rate of production can, in theory, continue indefinitely without any specified constraints.
