Senior high school function problem seems to require guidance, but I'm only a freshman in senior high school. Who will do it? Thank you Let the definition field of function f (x) be [- 1,0) U (0,1], and f (- x) = - f (x). When x belongs to [- 1,0], f (x) = 2aX + 1 / x ^ 2 (a is a real number) (1) Find the analytical formula of F (x) when x belongs to (0,1] (2) If f (x) is an increasing function on the interval (0,1], find the value range of A (3) Find the maximum value of F (x) on the interval (0,1]

I'm senior 3. Let me answer for you. Ha ~ (1) when x belongs to (0,1), - x belongs to [- 1,0]. At this time, f (x) = - f (- x) = 2ax-1 / x ^ 2 (2) when x belongs to (0,1], f ^ (x) = 2A + 2 / x ^ 3. Because the function is an increasing function, the derivative is always greater than zero in the interval, that is, 2A + 2 / x ^ 3 is greater than equal to zero, which is always true in the interval, so

If the domain of function f (x + 1) is (- ½, 2) , then f (x ²) The definition fields of are: - ½＜ x＜2 ∴ ½＜ X + 1 ＜ 3 I want to ask how is this? Because x adds 1. So both sides also add 1? The definition field of F (x) is（ ½, 3) This. Just now, the top is not x + 1. X. if it is understood that these are two different functions, how can we use the upper function to solve the lower function then ½＜ x ²＜ Why isn't this one like the one above? Why is there no square on both sides? I'm sorry. But I haven't been in touch for too many years. Recently, I have to use function knowledge. So I read it wildly.

When I was in high school, I was also very confused, but in fact, there was nothing to understand
The letters x, y and Z in the equation represent unknowns and are fixed. What is found is how much
But the function is different. The letters in the function are just the symbols of variables, f (x + 1), f (x), f (x) ²) X in is not the same, but f (x) and f (y) actually represent the same function and will not become another function because the sign of the independent variable changes
My ability of expression is limited. I don't know if you can understand what I said. If you understand it, you can understand the solution of this problem

1. Given the function f (x) = 2 ^ x-a / 2 ^ x, H (x) = 2-2 ^ (X-2) + A / 2 ^ (X-2), Let f (x) = f (x) 1 / A + H (x), know that the minimum value of F (x) is m, and M > 2 + √ 7, find the value range of real number a 2. The image of function y = KX (k > 0) and the image of function y = log2 (x) intersect at two points A1 and B1 (A1 is on the line segment ob1, and O is the coordinate origin). Through A1 and B1, make the vertical line of X axis, the vertical feet are m and N respectively, and a1m.b1n intersect the image of function y = log4 (x) and two points A2 and B2 respectively. If A1B2 is parallel to the X axis, calculate the area of quadrilateral a1a2b2b1

1. F (x) = (2 ^ x-a / 2 ^ x) / A + 2-2 ^ (X-2) + A / 2 ^ (X-2) = (1 / A-1 / 4) 2 ^ x + (4a-1) / 2 ^ x + 2 as an alternative t = 2 ^ x, since the value field of 2 ^ x is (0, + ∞), t > 0 (note that 0 cannot be obtained) because the endpoint value of the function definition field cannot be obtained, if the function has a maximum value, the maximum value must be obtained at the non endpoint (because

A very simple function problem in high school I can't understand the examples and answers in the book (1) Known function f (x) = x ², Find f (x-1) (2) Known function f (x-1) = x ², Find f (x) The first question I know, f (x-1) = (x-1) ²= x ²- 2x+1 Second, ask who will tell me

F[(x+1)-1]=(x+1) ²= x ²+ 2x+1=F(x)

A high school function problem, Given that the domain of function f (X-2) is (0,2], find the domain of F (2x-2)

The domain of F (X-2) is (0,2]
So 0
