This is the part 03 out of four lectures on this topic. The description of remaining three parts has been given below.
For best viewing switch video quality to 360p or 720p in your windows/android phone/browser.
You can find following content in the lecture.
If gof is one one then f is one one.
If gof is one to one.
If gof is one to one then so is f.
If gof is one to one then g is one to one.
If gof is one to one must f be one to one.
