Screencast on finding the domain and range of a function, and how to write domains and ranges in correct interval notation. For range, we focus mostly on graphical representations of functions.

um…you never really explained range before interval notation. but overall thanks for that :]

Thank you.

Thank you, Dr. Talbert for taking your time to make these. It really helped me get back into math after some years. YouTube is the best

THANKS!

Very good review, easy to follow and understand. Only criticism is that you could have explained the Union and its counterpart more. I suppose range as well. Regardless, very good.

very helpful, great explanation of domain, range, and interval notation. how did you get so good at writing so accurately in paint? lol

Thanks you sir!
