This is Tom from the Worldwide Center of Mathematics walking you through important and useful features of your TI-84 graphing calculator.
This TI-84 plus graphing calculator series is meant to be an instructional walkthrough that covers some of the most often used functions on a TI-84. This particular video covers graphing and shows the viewer how to graph functions, use the zoom feature and to find the intersection of two graphs. The software used in this video is TI-Smartview.

Thank you so much. I haven’t used calculator in a while and I’m taking calc for online school. This just refreshed all my memories!!!

[@jamisonmac06]

THANK YOU! I was having so many issues with graphing on the calculator but thanks to you I know how to graph on it.

[@TheWaynester101]

thank you so much! nobody at the math tutoring department of my uni could tell me how to do this. they just said "you just gotta figure it out" how am i going to have the time to manually draw two parabolas in a 2 hour calc test ? thanks again!

[@namaste_1236]

Plug in all the x values and trace

[@TheWaynester101]

@@namaste_1236 yup, i didn't know that

[@makaylahmorgenstern191]

I know I'm a junior in high school and it was killing me. Everyone knew how to do this but me.

[@expertmathtutoring5650]

I can always help!

[@tanyaparker-callsign.kk7ic238]

Thank you for this video it’s been a while since talking calculus and using a Texas instrument calculator. I purchased the TI-84 Plus from another video, but I like the color from yours it helps make learning interesting especially when relearning the calculator with its added features and written work refresher.

[@saiarodriguez1592]

Thank you!! I have a graphing calculator quiz coming up and i needed this!!

[@jakaylaa3946]

This helped me so much cause nobody would help me figure out why nothing was graphing correctly.

[@quinnomeed1458]

Thank you much man, I lost the instructions so this is a big blessing.

[@elmoreglidingclub3030]

Got it!! Good stuff; it’ll get me started enjoying my old TI-84+!!

Thnx Sir !!!!!! May God bless you 😀

Does anyone know if he uploaded videos demonstrating examples of the other types of functions: polar, parametric, and seq?

Thankyou!!!

thanks!!

[@Paquito191]

So how do I get rid of the X , Y when I see my graph. Like I only want to see the graph not the X and Y on the right side .

[@raze891]

thank you

[@noelle9853]

how do u move the graph around? i cant see the full line

[@thedirt3noob412]

watching this 30 mins before a national exam

Thx

[@ethanrasmussen4061]

so damn mad. why does it either say syntax error or says the range is too great?

[@ruchirrawat8804]

Can we find maxima and minima of the equations we input ?? I need it desperately for SAT

[@dogsrpeople2164]

Yeah, press window

[@thecmdcoolmandude]

What if my second line/curve doesn’t work

[@joannesparkes6140]

I'm a teacher and wondering what is the name of the software you are using to display this to students?

[@Yahya-vk2we]

I think you can search ti-84 emulator then download one

[@steambun3431]

hi, how will you graph if there Y in it for example 3x + 4y = 12

[@centerofmath]

You solve for y and graph y = (12 -3x) / 4

[@roryg9220]

Thanks man!

[@zoemotteram2346]

It won't let me have a negative and a positive equation a the same time "syntax error", I really need the calculator to do this

[@ullaredskjell]

Same :/

[@hughsilva5655]

When I press y+ they are all "r" instead of "y", wtf?

[@frangotino]

go to "Mode" and change the 4th option to "FUNC" or "Function"

[@Artimes.]

Man i have seen like 5 of these types of video's and No one has mentioned about how to enter a function equation after running a regression and then getting a graph. Like i know how to enter it manually but that just takes to much time. Its much quicker if you run a regression and add that function to your regression so you can plot your graph.

[@ibrahemalariki7204]

This is cool

[@morakano3355]

I want to fire so many teachers in this country. How can they force us to buy this expensive device not knowing how to use it. They even never ever use it for their course.

Just saying, I have 0Y to 9Y
