Let f (x) be defined as D. if there is a non-zero real number m such that for any x ∈ m (M is contained in D), there is (x-m) ∈ D and f (x-m) ≤ f (x), then F (x) is a low-key function of degree m on M. if f (x) whose domain is R is an odd function, when x ≥ 0, f (x) = | X - A ^ 2 | - A ^ 2, and f (x) is a low-key function of degree 5 on R, then the value range of real number a is?

F (x) is an odd function, so f (- x) = - f (x)
So, when x = 0, | (X-5) - A ^ 2 | - A ^ 2 A ^ 2 > = 0, X-5 > = 0 ------ > A = 0
0
