Use Piecewise. I don't know what value you want when x is outside the domain you specified. I used 0. f[x_] := Piecewise[{{150, 0 < x <= 15}, {x^3, 15 < x <= 24}}, 0] Plot[f[x], {x, 0, 24}, Frame -> True, Axes -> False] David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ From: MANOLIS VOSKAKIS [mailto:emperor_mvs at hotmail.com] we have an equation tha is divided in to sub equations f=150 when 0<x15 f=x^3 when 15<x24 how can i create a plot in mathematica?? i want all in 1 graph thanks alot manoli
