The typical voltage, V $,$ in volts $(V),$ supplied by an electrical outlet in Cuba is a sinusoidal function that oscillates between $-155$ V and $+155$ V and makes $60$ complete cycles each second. Draw a graph beginning with the minimum voltage on the $y-$axis and show one complete cycle. Then, determine four possible sinusoidal equations for the voltage, $V,$ as a function of time, $t,$ using a minimum horizontal phase shift.
