This graph has the shape of an inverse variation function, which has an equation of the form $\displaystyle{y}=\frac{{k}}{{x}}\usepackage{cmbright}\Huge\$ . This graph shows the function $\displaystyle{y}=\frac{{6}}{{x}}\usepackage{cmbright}\Huge\$ . All of the points on the curve of the function--including (1, 6), (2, 3), (-1, -6), and (-2, -3)--satisfy this function.
