Hello everyone, i'm having some troubles figuring this out. I'm supppose to Describe the set of points whose coordinates satisfy the given equations and inequalitites. Sketch the graph. x^2 + y^2 + z^2 ≤ 16, 2 ≤ y ≤ 4; I forgot the rules of inequalitites, I see its an equation of a sphere and the plane is going to be parallel to the xz-plane but i'm lost after that. Any help would be great! thanks!
