How to plot 2 different functions

HP Recommended
HP PRIME

Hello!
I can't figure out how to plot these 2 different functions simultaneously:

because it draws only the second function in the "Function" app. If I try to plot them in the "Advanced Graphing" app, then it draws only the first one.
Is there any way to combine them?

Oh. I just  had to write the second equation as Y = 2/3 X :smileyembarrassed:

Your first equation in the Function app is not a function.

 

An example of a function is: F1(X)=SIN(X)+3*X^2 +3.7, in which case you only have to enter: SIN(X)+3*X^2+3.7

 

So in the Function app you never must use the equal sign: =

 

It is allowed to use Y, but this is confusing because the Function app will consider it as an ordinary constant, like any other variable that you could use, eg A or B.

 

For general relations between X and Y you can use the Advanced Graphing app.
