1. For each differential equations below, state whether the differential equation is separa- ble or not. If separable make sure to write it in a separable form (that is g(y) d = h(x)). Clearly justify your answers and show your work. dx dy xex a. dx yV1+ 32 dy b. C. d. dx dx dy da = 4x - y + y = 3xy y-5 3
