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.
Biorenewable polymers such as natural cellulosic fibers have been the subject of study in both native and modified form for a variety of applications starting from biomedical to defense (Banerjee et al., 2013, Rangel-Vazquez and Leal-Garcia, 2010 and Thakur et al., 2013a).
