Domain and Range of Composite Functions Part II

In this video I will introduce you to finding the domain and range of a composition of two functions. We'll be focusing on simple rational functions in this first video, and I will take you through a visualization that I use to understand how the two functions interact. In the second video of this series I will look at some other compositions involving radicals and linear equations.

this was actually the most clear and helpful way i've seen this explained. Thank you!

As a non bias viewer (British, not American) I can say that this is the most helpful video I've seen today when it comes to this mater, very well done

Loved this video. Am teaching this as part of the new syllabus in Australia. I haven't seen your process done so clearly anywhere else.

Great video!! makes the process seem logical and easy to understand, thankyou!!!

Very useful. (I'm a maths teacher looking for best practice). Many thanks.

Hi! sorry for the late question, but why isn't the domain for the last composite function [0, 3]? we have already established that the -3 of [-3, 3] cannot be entered into g(x) as the range of f(x) is the domain of g(x), please do correct me if I'm wrong I'm pretty bad at this topic. Thank you very much for this upload it has helped me loads :)

Sir plz can u tell me the domain and range of fog(x) and gof(x)
