Solution

The output voltage of an inverting amplifier is given by the formula Vout = -A * Vin, where A is the gain of the amplifier and Vin is the input voltage.

Given that the gain A is 1, the output voltage for each input voltage will be:

For Vin = 1.2 V, Vout = -1 * 1.2 V = -1.2 V For Vin = 3.2 V, Vout = -1 * 3.2 V = -3.2 V For Vin = 4.2 V, Vout = -1 * 4.2 V = -4.2 V

So, the output voltages for the given input voltages are -1.2 V, -3.2 V, and -4.2 V respectively. Therefore, the answer is d. -4.2 V.
