This curve fits the general shape of a logarithmic graph: it gets close to the y-axis for x near 0, increases as x increases, and is curved downward. Create a table of values for the function $\displaystyle{f{{\left({x}\right)}}}={\ln{{6}}}{x}\usepackage{cmbright}\Huge\$ and check it against this graph. For example, the graph should go through $\displaystyle{\left({1},{\ln{{6}}}\right)}\approx{\left({1},{1.8}\right)}\usepackage{cmbright}\Huge\$ and $\displaystyle{\left({2},{\ln{{12}}}\right)}\approx{\left({2},{2.5}\right)}\usepackage{cmbright}\Huge\$ . It does.
