TI-84 Plus Graphing Calculator Guide: Graphing functions

You can jump to a specific topic by clicking one of the links below:

Graphing a function: 0:22
Zoom: 2:26
y-intercept and x-intercept: 3:29
Minimum and Maximum values: 6:10
Intersection of graphs: 7:35
Parametric and Polar coordinates: 9:33

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!!!

[TheWaynester]

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!

[jamisonmac]

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

A decade later and this is still helpful!

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

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

[elmoreglidingclub]

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

[jakaylaa]

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

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.

Thank you, I was having problem with finding zeroes for my maths 2 subject test. Super helpful

[tituswillb]

thanks so much! this will be so useful for my precalc class :)

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

[ruchirrawat]

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

[thedirtnoob]

watching this 30 mins before a national exam

[Paquito]

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 .

[joannesparkes]

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

[noelle]

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

[steambun]

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

[ethanrasmussen]

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

[hughsilva]

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