Knows somebody to draw a function to pieces?
For example:
and = x - 2 if x < 2
and = x + 3 if 2 < x < 3
and = 7 if x > 3
I have tried it of a pile of forms and I am not able

Hello Abel, this I obtained the forum classpad in English, can that helps, at least allows you to specify the dominion for a function and you can use several of these intrucciones

y=sin(x)|-2Pix

In the example that you propose it would be:

y=x-2|2>x
y=x+3|2x
y=7|3
Perhaps in addition piecewise is of utility the function (literalmnete is ' to pieces ').

Salut

I have seen that the lines are cut that take ">" or "<"

The symbol "|" as is, the one of absolute value (keyboard/mth/OPC)?

Graph "y=7|3" but I did not obtain the awaited results?

Hello Betoe, which happens is that when you combine "|" with "<" or ">" the characters are cut in the screen, I will send the text to you by email since I did it for Abel

I have been investigating and leaves perfecvto writing:
y=x+1|x<-1
and = x+2|x>-1|x<2
y=x|x>2
The lines are not cut to me, as you said, leaves to me perfect?

and = x - 2  if x < 2
              and = x + 3    if    2 < x < 3
              and = 7          if x > 3

I think it can help:
y=piecewise(x:lol:
