Consider a (not necessarily bounded) convex polyhedron $P\subset \mathbb{R}^n$ which has $k$ facets. Let $L:\mathbb{R}^n \to \mathbb{R}^m$ be a linear transformation. **Question1:** Is there a fixed constant $C$ such that the number of facets of $L(P)$ is bounded by $Ck$ ? **Edit:** **Question2:** Is there any bound on the number of facets of $L(P)$ in terms of $P$?
