| Description: A constant function expressed in maps-to notation is polynomial. This theorem and the several that follow (mzpaddmpt 42848, mzpmulmpt 42849, mzpnegmpt 42851, mzpsubmpt 42850, mzpexpmpt 42852) 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 42844 is already expressed using maps-to notation. (Contributed by Stefan O'Rear, 5-Oct-2014.) |
