How do I get rid of the private browsing option...I have teens and don't want this option on my computer.

I want to be able to track the history on my computer. I do not like the idea that my teens can use the private browsing option, and there will be no history for me to check. As a parent, I think it is important to be able to check what has been viewed on my computer. How can I get rid of the private browsing option?
