Graphing Piecewise Functions with Desmos

[@captainfriedrich]

Sir, you don't even realize how much this saved me... Thank you so much for your help

[@eriklokensgard7487]

Good idea! I had just sort of assumed that Desmos didn't care about showing whether an inequality included or excluded a given point, and didn't realize that there was a built in feature to illustrate that if we want to create our own clear piecewise functions. Thank you for sharing!

[@martinlee6331]

Thank you. This makes so much sense, especially having the open and closed circles ON the graph. Such a time saver!!!!!!!

[@ocean_night1531]

Thank you so much! It's been so long since I've had to use desmos regularly that I'd forgotten how to do this! You're a lifesaver!

[@saddenedkermit]

thank you so much!! such a big help you don't understand

[@tolanCode]

can also be done with this syntax all on one line instead of breaking into three lines:
f(x) = { condition1: equation, condition2: equation, condition3: equation}
so like:
f(x) = {x

It works

[@AngieTeaches]

I love this! Thanks for sharing

[@LydellAaron]

I wanted to learn this. Came across their sign(x) function for steps but this is still necessary. Thank you!

[@danielhill2531]

Thank you so much, best person who has taught me this

[@gaurivandana4660]

you helped a lot. i was struggling for days.

[@hamzaalaudi1184]

thank you, I was looking around for this and this video helped a lot

[@wolfy-chann]

Thanks man I appreciate you 🥰

[@syedtaha2222]

Thank you for the saving my life

[@StudywithmeinPakistan]

Wonderful. Watching from Pakistan

How to give curly brackets in desmos mobile app

[@sandracornell5396]

How did you put in the curly brackets to enter the domains?

[@Dragonometry]

The brackets are available near the bottom of the ABC keyboard. To limit the x-values, write a compound inequality with x in the middle.

[@DavidNintang]

Thank you!

[@LathaLatha-si6ti]

Thank you...🙏🏻

[@erikev]

This is not really a piecewise defined function. It is just 3 different functions. You have to be able to use f(x) new expressions, like g(x)=f(x-2)f(2-x), and this does not work.

[@Dragonometry]

Our goal was to get a picture of our functions in Desmos, not to create a function object, but I see what you mean.

[@evilshep1581]

@@Dragonometry Is there a way to do it in TI-89 style where you use the "when( " function where you can type it all in one row?

[@Dragonometry]

@@evilshep1581 good question. I have not come across that functionality, not yet at least.

[@nkoo2999]

Thank you really helped me

[@behtrm]

It seems that desmos doesn’t natively support piece wise functions all that well as you had to use this weird workaround. Thank you for the guide though!

[@ericlayton913]

Thanks for sharing this!

[@ATIF_YT-ty8gg]

Thanks a lot

[@akashyadav8896]

Thanks man

[@Godislove-o3d]

i love it

[@toufik11101]

Dear sir, I take class in online in an Edtech, I want to use the screenshot of the graph with function, I ask your kind permission.

[@jaemiedayag5706]

It isn’t working :((( im crying rn

[@y_p7]

Thanks may Allah (swt) bless you

[@batayolajarrenjoses.5242]

is this continuous or discontinuous

[@gregoryharlston0602]

It's discontinuous! If you were tracing out the graph with a pencil or your finger and can get from the start of the function to the end of the function WITHOUT lifting your pencil or finger off the paper or screen, it's continuous. Otherwise, it's discontinuous.

[@B00MBUS]

Depends if your talking about continuity at a point or continuity over an interval

[@Joao456Zamper]

This is good for plotting, but if want f(4), it won`t give me

[@Dragonometry]

Yeah, this was just meant to create the picture of the function, not produce function values.
