  • YOU HELPED ME SO MUCH!

  • @nodymnds4u Glad to help out! Shetts

  • The domain BEFORE 8:30 in the video is from -4 to 6, So that is written in interval notation as[-4,6).

    For the range you collapse the graphs to the y axis. Note there are single points on the y-axis at -3, -1, 1, 3, and 5. How is this written in interval notation?

    Like this [-3,-3], [-1,-1], [1,1], [3,3], [5,5]. I know it is a little silly to write it this way and much easier to simply list the numbers.

    Hope this helps,

    If you have anymore questions, please ask!

  • Super helpful!

    

  • I just started teaching precalculus this year and this video was abolutely masterful. Not only was the explanation of the domain and range very clear, but the translation to interval notation is exactly what my students need at this time. I plan to make a video response to this of one I made that goes along with your wonderful video.

  • ya, i think, pls create harder examples..

  • :( ??

  • this is good for beginners, but it won't work for much harder ones, triple composite functions involving inverse etc.

  • I love your loud voice it make me understand better.
