Correct. Since y is an inverse function, $\displaystyle{y}=\frac{{k}}{{x}}\usepackage{cmbright}\Huge\$ , so $\displaystyle{y}=\frac{{k}}{{3}}\usepackage{cmbright}\Huge\$ when x = 3. Then $\displaystyle{k}={7}\cdot{3}={21}\usepackage{cmbright}\Huge\$ , so when x = 6, $\displaystyle{y}=\frac{{21}}{{6}}=\frac{{7}}{{3}}\usepackage{cmbright}\Huge\$ .
