In this discussion, we will explore stretching and shrinking a graph, both vertically and horizontally. When you finish studying this lesson, you should be able to do a problem like this: GRAPH: [beautiful math coming... please be patient] $\,y=2{\text{e}}^{5x}\,$.
According to how it is treated, cellulose can be used to make paper, film, explosives, and plastics, in addition to having many other industrial uses. The paper in this book contains cellulose, as do some of the clothes you are wearing. For humans, cellulose is also a major source of needed fiber in our diet.
Cellulose is basically plant fiber, and one of the most common sources is wood pulp. Manufacturers grind up the wood and extract the cellulose. It's odd to imagine the same kind of pulp that's used to make paper turning up in our food. So, it's no surprise there's buzz over a spate of recent posts, from Quartz to the Los Angeles Times, on the food industry's widespread use of cellulose to help add texture and fiber to foods.
