This is another exponential decay function and has the same shape as the given graph, but it is not an exact match. For example, this function would pass through the points $\displaystyle{\left(-{3},{27}\right)}\usepackage{cmbright}\Huge\$ , $\displaystyle{\left(-{2},{9}\right)}\usepackage{cmbright}\Huge\$ , $\displaystyle{\left(-{1},{3}\right)}\usepackage{cmbright}\Huge\$ , and $\displaystyle{\left({1},\frac{{1}}{{3}}\right)}\usepackage{cmbright}\Huge\$ , and these points are not on the given graph.
