Exercise 15

How can you extract data from a line plot The process is simply the reverse of the way you just learned to create the graph. You draw lines from the axes to where they intersect on the graph at the point whose value you want to know.
Let's look at figure.
FIGURE
Growth of Tetrahymena.

• How many cells were there at the half point of the growth curve
• How does that result compare to the cell population three hours earlier
• When did the growth of this population start to slow
A curve, such as this, that increases slowly at first but then rapidly accelerates is called a logistic curve. We'll discuss the mathematics that create this pattern in chapter 6.
