how long does it take to complete function section of math ?

Hi there!

Thank you for your question - although we currently do not provide a time tracker that defines the duration of our courses, this is certainly a good idea to help students structure their study plan and we will take it as feedback.

That said, it is worth noting that there is no estimated time frame regarding how long a learner should take in a course on Khan Academy. For this reason, I encourage you to learn at your own pace, as it is one of the missions Khan Academy has as a learning platform.

Wishing you all the best in your studies! I also recommend you click here and check out seven tips for making the most out of Khan Academy. It will definitely help you through the beautiful world of learning!
