Domain and Range of a Function From a Graph

This precalculus video tutorial explains how to find the domain and range of a function given its graph in interval notation. The domain represents all of the x values in the function and the range represents all of the y values. You should use parentheses for open circles and infinity symbols but you should brackets for closed circles. This video contains plenty of examples and practice problems of finding the domain and range of a graph.

[@bellaroo1995]

When you have a student teacher that sucks so much it’s almost impossible to focus, plus she sucks at explaining and takes up half the period explaining 1 problem, and your REAL teacher that everyone likes just decides to not teach at all. Bam here I am not understanding anything 😑😑

[@imaneboualam7566]

I would like to take a moment and thank you from the bottom of my heart for all the time and effort you put in all your videos, I love the way you explain and make the problem seems easy to solve, you are a master!!!!!!! I really can't thank you enough, math is not my best subject but I start to like it now. And guess what? I have got an A because of your videos.

I love how this youtube channel simplifies math in an easier and understandable way but the actual teachers has to make it seem hard for no reason

[@hiiii2873]

My teacher is an asshole. I just became a freshman and this one teacher acts like were adults and will embarass a student for asking a question claiming they arent paying attention, and if we try to defend ourselves they'll start talking over and be like "OKAY NOW CLASS NEXT PROBLEM" they'll also cuss students out and call them names, I regret not switching classes.

[@hiiii2873]

Also they'll tell us to take notes but they talk really fast on purpose so if u turn ur attention span away from the board and try to take notes to remember, ur just stuck honestly

You are a really great teacher. I've seen other videos like Khan Academy, and full algebra videos, but I always come back to your channel for a simplified version. Thank you for this ❤️

[@leahshuster3412]

You are absolutely brilliant and I love the way you teach. You are the greatest teacher I have ever seen. Unfortunately my math teacher is 18 years old which makes things difficult. I am super thankful for all your hard work and effort. You explain the material crisp clear, no one can get better than you. Your videos are 1000 times better than my long classes in school. I have been learning the same topic for two weeks in school and when I got home i watched your videos and fully understood it. You make learning so enjoyable and fun, and I can seriously watch your videos all day long. Thank you!!!

[@emaking528]

I love you, prof.! You're the best! And I agree with what you said that the best way to learn is by examples. Most of my teachers in math just blabber about the rules, the meaning, and whatnot, but just give a few examples. But to you, even though I don't know the terms, you always remind me of what they mean in between the examples. You save my time, and you give me knowledge easily! Lots of examples taught me how to solve different problems. You're the best! Thank you!!

hello tutor, nice videos you put out there. in regards to the domain and range, is there a way to find them directly from the function given? or do you have to plot the graph every time? many thanks in advance.
