GRAPHING IN THE REAL NUMBER PLANE

In this particular section, you are going to see how certain mathematical procedures can be used to study the growth patterns of living organisms. An amazing discovery about living organisms (microorganisms, plants, or animals–including humans) is that all have quite similar growth patterns. We shall investigate these growth patterns with a population of mold, but first we need to know some additional mathematical procedures.
