Doubt in changing signs of velocities?????

In Gene f=+)t Vo (v+V)TVsJ Apparent frequency In case of stationary medium v = 0 f's VVolt vTVsJ where Vo Observer velocity Vs SOurce velocity f actual frequency V = velocity of sound ) When source moves towards stationary observ Vs+) S O V-Vs i) When sources moves away from stationary obs Vs(-) S O f'= v LV+ Vs (ii) When observer moves towards stationary source= Vo-) S O
