Plot multiple functions

[anestiszlatkos]

hi, iam new in the community.
i would like to ask how to plot two different functions with different intervals

for example

y=3x+3, x>=2

y=5x+2 x<1

You could use Show to “merge” plots

Show[
 	Plot[3 x + 3, {x, 2, 4}],
 	Plot[5 x + 2, {x, -2, 1}],
 	PlotRange -> All, AxesOrigin -> {0, 0}
 ]
