If a graph is periodic, what would you expect to see for x-values less than -2 and greater than 20?
If a graph is periodic, it means that it repeats a specific pattern over and over again. Therefore, if a graph is periodic, we expect to see the same values for the x-coordinate (x-values) repeating as well.
If x-values less than -2 and greater than 20 fall outside of the initial pattern or range of the graph, we still expect them to follow the same pattern and replicate the values within the periodicity.
In other words, for x-values less than -2 and greater than 20, we would still see the same values repeating as we would within the primary range of the graph.
