The fixing number of a graph G is the order of the smallest subset S of its vertex set V(G) such that stabilizer of S in G, ΓS(G) is trivial. Let G1 and G2 be disjoint copies of a graph G, and let g:V(G1)→ V(G2) be a function. A functigraph FG consists of the vertex set V(G1)∪ V(G2) and the edge set E(G1)∪ E(G2)∪ \uv:v=g(u)\. In this paper, we study the behavior of the fixing number in passing from G to FG and find its sharp lower and upper bounds. We also study the fixing number of functigraphs of some well known families of graphs like complete graphs, trees and join graphs.
