Question

Quick question about graphing calculator. Writing below:

Answer 1

I have a TI-83 Plus. Here's the question:

On the "Y=" screen you have Y1, Y2, Y3, etc.

If you have multiple graphs entered, how can you choose just one of the graph to show up on the graphing screen?

Answer 2

Remove 'delete' the other two equations from the "Y=" screen.

Answer 3

well i am doing composite functions so i have an equation for y1, a differnt equation for y2, and then my y3 is "y=(y1)+(y2)

Answer 4

i just want to show the graph of "y=(y1)+(y2)"

Answer 5

That I'm not sure how to do that, I have a Ti-84+. Is there a reason why you want just the "y=(y1)+(y2)"?

Answer 6

because we are doing composite functions so i just want the composite graph. For example:

f(x)=2x+3
g(x)=(x-3)^2

find f(g(x))

Answer 7

so i want to check my answers by using the calc. see what i mean?

Answer 8

@Hero

Answer 9

Ok I think there is an option you can do, if you hit trace and then use the up/down arrow keys you can switch which equation you want.

Answer 10

hmmm i see what you are saying but i know there is a way to have just one graph appear

Answer 11

Well sorry, you could take a look on Texas Instruments website to find an answer or your calculator manual.

Answer 12

thanks for your help, ill go check there

Answer 13

You can chat with a Texas Instruments rep or just call them I'm pretty sure they will speak to you for free about it.
