Question

A scientist wanted to compare the growth rate of mold on a muffin. At the start of the experiment there are 12 mold cells. Each time a periodic observation is made, the number of mold cells increases by 8. For example, at observation #1, there are 20 mold cells.

Answer 1

In this experiment each time he chack the mold cells there are 8 new cells so the first time he saw 20 cells, then 28 cells then 36 cells and so on.

So in this case the increase of the population is constant so in this case is not an exponential growht, is bether a linear growht
