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]

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
