Description: A constant function expressed in maps-to notation is polynomial. This theorem and the several that follow (mzpaddmpt 42225, mzpmulmpt 42226, mzpnegmpt 42228, mzpsubmpt 42227, mzpexpmpt 42229) 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 42221 is already expressed using maps-to notation. (Contributed by Stefan O'Rear, 5-Oct-2014.) |
