So my book has a bunch of examples of graphs similar to sine or cosine graphs, where the maximums and minimums are the same (for example, the maximums might be 1, and the minimums will be -1).
If I only have a graph to work with, I will just look at the waves and determine the period from that. But how do I determine the period of a graph that has unequal maximum and minimums? For example, all the maximums may be 7, but all the minimums will be 2. How do I determine the period of a graph like this, if I only have the graph to work with? Do I just move the graph so that its center is at the x axis? Is there anyway to determine the period of a graph like this without using graphing software to reposition the graph to the x axis? If I have to redraw it it could be difficult.
