Hello community, I'm new here and also a beginner in mathematica.
I want to do an RegionPlot in mathematica, but my provided inequality should hold over an intervall of a third variable. An example of my problem:
f[x_, y_, z_] = x + y*z;
RegionPlot[f[x, y, z] > 0, {x, -2, 2}, {y, -2, 2} for {z, -0.5, 0.5}]
Sorry, I know that it is not possible in this way however I hope that someone understand what I want to do.
Thank You for answering!
