1 This produces a vertical stretch, where the $\,y$-values on the graph get multiplied by $\,2\,$.  Replace every $\,x\,$ by $\,5x\,$, giving the new equation [beautiful math coming... please be patient] $\,y=2{\text{e}}^{5x}\,$.
The human body contains many natural polymers, such as proteins and nucleic acids. Cellulose, another natural polymer, is the main structural component of plants. Most natural polymers are condensation polymers, and in their formation from monomers water is a by-product.
Polymers are of two types: Natural polymeric materials such as shellac, amber, wool, silk and natural rubber have been used for centuries. A variety of other natural polymers exist, such as cellulose, which is the main constituent of wood and paper.
