If the domain of F (X & # 178;) is [- 1,1], the domain of F (x) is

∵ f (X & # 178;) is defined as [- 1,1]
The definition field is the value range of X
The value range of X & # is [0,1]
And the range of values of ∵ () is the same
For f (x), X ∈ [0,1]
That is, the definition field is [0,1]

11. If the definition field of function f (X & # 178; - 1) is [- 1,2], then the value range of X in function f (√ x) is X ∈ [- 1,2] → X & # 178; - 1 ∈ [- 1,3], ■ √ x ∈ [- 1,3] → x ∈ [0,9]. I don't understand how X & # 178; - 1 ∈ [- 1,3], and then get x ∈ [0,9] It's a bit confusing. Is the analytic expression of F (X & # 178; - 1) and f (√ x) the same, with the same range, but the whole (X & # 178; - 1, √ x) as X is different, so the definition field of X in that whole is required

16. Let f (x) be defined as (- L, l). It is proved that there must exist even function g (x) and odd function H (x) on (- L, l) such that f (x) = g (x) + H (x) Suppose g (x) and H (x) exist, such that f (x) = g (x) + H (x), (1), And G (- x) = g (x), H (- x) = - H (x) So f (- x) = g (- x) + H (- x) = g (x) - H (x), (2) Using (1) and (2), G (x) = [f (x) + F (- x)] / 2 h(x)=[f(x)-f(-x)]/2 Then G (x) + H (x) = f (x), g(-x)=[f(-x)+f(x)]/2=g(x), h(-x)=[f(-x)-f(x)]/2=h(x). I can't understand the proof process of this problem. He first assumes that G (x) and H (x) exist, and satisfies f (x) = g (x) + H (x), and obtains formula (2). Then he uses the conclusions (1) and (2) obtained from the hypothesis to prove that the original hypothetical sentence is true. How can the proof be correct, The last line should be h (- x) = [f (- x) - f (x)] / 2 = - H (x)
