Recursive Function is URM Computable

Theorem
Every recursive function‎ is URM computable.

Proof
From: it follows that all the functions obtained from the basic primitive recursive functions using the operations of substitution, primitive recursion and minimization (on a function or a relation) are URM computable.
 * Functions obtained by minimization from URM computable functions are URM computable
 * Functions obtained by minimization from URM computable relations are URM computable
 * Functions obtained by primitive recursion from URM computable functions are URM computable
 * Functions obtained by substitution from URM computable functions are URM computable
 * Primitive Recursive Function is URM Computable
 * Primitive Recursive Relation is URM Computable
