Both this function and the graph have an amplitude of 5. However, the period of this function is $\displaystyle\frac{{{2}\pi}}{\pi}={2}\usepackage{cmbright}\Huge\$ , while the period of the graph is 1. Also, the graph of this function does not pass through the point $\displaystyle{\left(\frac{{1}}{{2}},{5}\right)}\usepackage{cmbright}\Huge\$ .
