Graphing Piecewise Functions

This video looks at graphing piecewise functions. It includes two examples.

6 years later you have the new generation watching this.... Thank you for this Sir

[@MartyBrandl]

You're welcome! Math never gets old! 😉 Keep working hard! 👍

[@user-wl4kf7vq5n]

I studied this concept two days in a row and still could not understand it at all. There were no good explanations anywhere, I tried several other youtube videos which were no help for me. They always over-complicated the subject. I even went over it several times with my teacher. But this video was the only thing that helped! You went through the full process and broke it down in a way that I could understand and it makes complete sense to me now! Thank you so much, Mr. Marty! You earned a subscriber!

was stuck on this for an hour, searched for so many tutorials and none of them worked. thank you for this man.

this is the best explanation ever!!! I've tried a lot of channel for weeks and still couldn't understand, but when I watched this all my brain cells came back to life

[@LuvllyAkiria]

I'm so grateful for this video. I had been studying this for 2 days & my instructor was unreachable as her office hours are from 8:30-10am on Tuesday & Thursday & tomorrow is when the assignment is due & I get stuck on the last part 27 after completing 1-26, smh. No other youtube videos explained it as simple & understanding as you sir. Thank you!

You can do it! Watching videos like this will help you to understand it. Hang in there! 👍

[@jesusice601]

@@MartyBrandl ive had 200000 mental breakdowns in the past 7 hours but thanks for the encouragement 😂

[@MartyBrandl]

@@jesusice601 That's an incredible breakdown rate! My main advice is to forget the conditions and just graph each individual line. Then bring in the conditions to grab just the parts of the graph you are interested in. Have you used Desmos before? That's an incredible tool for working with graphs. If the breakdown rate doesn't lessen, you may want to get that checked out. 😉 Hang in there!

The domain is the x-values, so you could fold the graph to only see the horizontal number line.

What if it’s: “-x + 1, if x < 0.” I don’t get what you do when X is < or > 0.

[@Stoneface_]

No solution, I think

[@MartyBrandl]

So it's saying that when x is negative use -x + 1 to get a value. If there aren't any other pieces, then the function would be undefined for x >= 0. I hope that helps! Thanks for asking! :-)

[@ahmadmhmd5465]

Thank you but can we add the two piecewise function

[@jose8a_centeno]

[@Shadow-mf7jw]

Why are you using 2 as x? For example, can’t you use 1 for the first equation?

[@MartyBrandl]

Because 2 is the change-over from using one expression to the other, so that's where things are interesting. You certainly could use 1 in the first equation. I hope that helps! Keep after it! 👍
