Quadratic and Cubic inequality using Casio FX-991ES Plus C

[@userisunknownn]

I have the same calculator but it’s doesn’t work 💔

[@equaser]

may be it does not have the "plus" or the "C"

[@madeenamariam2646]

even for me it doesn't work

[@9.6431]

I figured that you can do it by clicking MODE ( 5 - 3 ) and input the numbers and vuala

I'm not getting it with same calculator please

[@YnM.2185]

Our teacher gave us this:
x²-2x+2≤P(x)≤2x²-4x+3
We know that P(11)= 181
We have to find P(16)

[@equaser]

this calculator can give you true or false.

Your not showing the whole complete calculator step by step !

[@equaser]

When you don’t watch and skip the video that is what you get

[@erickadawson5106]

[@OpeleyeEmmanuel-rg1ib]

How did you see the inequality mode in the Casio..

[@equaser]

that is this video about? I have shown how to go there and use it.

[@cedrickbryllsison5023]

Wbat software are you using in the graph

[@equaser]

You made me watch video to see if I mentioned it and indeed when I first showed the graph I mentioned desmos.com

[@Yavanist]

I tried it doesn't work out

[@equaser]

What the Doesn’t work? You did not find the inequality or the the answer is incorrect? If you did not find it then your calculator is different

[@Michelle-xt1rb]

If you can’t stand the heat, stay out of the kitchen 😅

[@Michelle-xt1rb]

I watched the whole video, how else can I comment on it ?

[@equaser]

than you got it.

Thanks for letting me know, even though the image of videos show only the C version but I changed the title and left only the C
