Which is not a government function in a mixed economy?

Buying factors of production from firms.

Explanation:

A mixed-capital company is a company that results from the union between the government of a country and private entities. Usually, but not necessarily, the company's capital is opened, with shares traded on the stock exchange, and shared between individual shareholders and / or legal entities.

Although these companies have, in the main, public capital, they are not legally considered public enterprises, so the production buying factors of these companies are not the responsibility of the government.
