This curve fits the general shape of an exponential graph: it gets close to the x-axis as x becomes more and more negative, increases as x increases, and is curved upward. Create a table of values for the function $\displaystyle{f{{\left({x}\right)}}}={{e}}^{{{0.2}{x}}}\usepackage{cmbright}\Huge\$ and check it against this graph. For example, the graph should go through $\displaystyle{\left({0},{1}\right)}\usepackage{cmbright}\Huge\$ and $\displaystyle{\left({5},{e}\right)}\approx{\left({5},{2.7}\right)}\usepackage{cmbright}\Huge\$ . It does.
