Here is the problem:

The PMOS transistor in the circuit below is conducting.

(a) Is V_TP > 0 or V_TP < 0 for this transistor?

(b) Based on this value of V_TP, what type of transistor is in the circuit?

(c) Is the proper symbol used in the circuit?

(d) If the symbol is incorrect, which symbol should be used?

Here is the circuit:

Here are transistor symbols in my textbook:

Here are PMOS transistor equations given in my textbook:
