Final answer:
The Arizona real estate commissioner can hire and fire department employees, inspect records, and investigate complaints, but likely cannot unilaterally revoke licenses without due process.
Step-by-step explanation:
The question pertains to the duties that the Arizona real estate commissioner is authorized to perform. Though the provided information does not directly specify the functions of the Arizona real estate commissioner, it is common in many jurisdictions that the duties of such an official might include hiring and firing departmental employees, inspecting business records of licensees, and investigating complaints against licensees. However, the unilateral revocation of licenses usually requires due process and may not be the sole decision of the commissioner but might involve a board or panel to review the complaint and decide upon the action to be taken. Thus, the action the Arizona real estate commissioner may not perform is likely the revocation of a license upon complaint of fraud without due process.
