Description: A constant function expressed in maps-to notation is polynomial. This theorem and the several that follow (mzpaddmpt 37825, mzpmulmpt 37826, mzpnegmpt 37828, mzpsubmpt 37827, mzpexpmpt 37829) can be used to build proofs that functions which are "manifestly polynomial", in the sense of being a maps-to containing constants, projections, and simple arithmetic operations, are actually polynomial functions. There is no mzpprojmpt because mzpproj 37821 is already expressed using maps-to notation. (Contributed by Stefan O'Rear, 5-Oct-2014.) |
