Provide an appropriate response.Suppose the population of deer fluctuates over time. The population increases in the summer and decreases in the winter. It also varies over many years as well. If you looked at the graph of population versus time, would this relation be a function? Why or why not?
What will be an ideal response?
This would be a function because at any given time there is only one possible population. Despite the fact that the population can reach the same level several times this is still a function, but for each point in time, there can be no more than one population.
