Is there a limit to number of Piecewise arguments allowed in W|A?

Hello:

In Alpha, I can successfully plot a piecewise function of 3 arguments but am unable to do so for one with 4 arguments.

Is this a systematic limitation or is there another way to plot?

Examples:

Plot[Piecewise[{{0.3* V,V<1000},{0.3* (1-.05)* V, 1000<=V<2500},{(0.3* (1-.05)^2)* V,2500<=V<3000},{(0.3* (1-.05)^3)* V,3000<=V}}],{V,0,4000}]

  • This does not work and returns, “Wolfram|Alpha doesn’t understand your query”

      Plot[Piecewise[{{0.3* (1-.05)* V, 1000<=V<2500},{(0.3* (1-.05)^2)* V,2500<=V<3000},{(0.3* (1-.05)^3)* V,3000<=V}}],{V,0,4000}]`

  • This works fine.

Thanks!
