Hi,

this makes absolutely no sense, because you will have no additional
information. Set k=p+q and you can do the same with only one parameter.
But your original question is easy:
Manipulate[
Plot[Evaluate[
Piecewise[{{x - p - q, x - p - q <= #}}, (x - p - q)^2] & /@
Range[6]], {x, 0, 20}, PlotRange -> {Automatic, {0, 50}}], {p, 0,
20}, {q, 0, 20}]
If you give Plot a list of functions you'll have them all in the same
plot. But I'm pretty sure you expected something different from this
plot.
Cheers
Patrick
