Answer:
5039
Step-by-step explanation:
Since a <em>bijective function</em> of a set onto itself is nothing but a <em>permutation of S</em> and the set
S={-44, -43, -42, -41, -40, -39, -38}
has 7 elements, there are 7! = 5040 possible bijective functions of S onto itself.
But there is only one such that φ(x) = x
Hence, there are 5040-1 = 5039 bijective functions of S onto itself such that φ(x)≠x.
