Step 1

The given circuit diagram and values of element is: Step 2

The modified circuit diagram at t = 0-: Step 3

The voltage across capacitor and the value of ix at t = 0- is determined as follows:

The value of capacitor voltage is equal to the supply voltage V2 because the circuit has been running for a long time before the switch flips.
