(b) Determine values of $x_{\mathrm{eq}}$, $A$, $\omega_o$, $f$, $T$, $\phi_o$ from the graph of $x(t)=x_{\mathrm{eq}}+A \cos(\omega_o t + \phi_o)$ shown below. Approximate answers to one or two significant figures are fine. Be sure to provide units for your answers!!! (Note that, in this class, we always require this but normally won't remind you.)
