It is known that the image of the line Y1 = x, y2 = 13X + 1, Y3 = - 45x + 5 is as shown in the figure. If no matter what the value of X is, y always takes the minimum value of Y1, Y2, Y3, then the maximum value of Y is______ .
As shown in the figure, the coordinates a (32, 32); B (259259); C (60173717) of the intersection of Y1, Y2 and Y3 are obtained respectively, when x < 32, y = Y1; when 32 ≤ x < 259, y = Y2; when 259 ≤ x < 6017, y = Y2; when x ≥ 6017, y = Y3. ∵ y always takes the minimum value of Y1, Y2 and Y3, ∵ y max = 3717
If f (- x) = - f (x), f (2a-x) = f (x), then t =?
Explain the detailed ideas and results
I can tell you, the result is 4a,
The purpose is to find out f (x) = f (x + T)
So f (x) = f (2a-x) = - f (x-2a) = - f (2A - (x-2a)) = - f (4a-x) = f (x-4a)
The solid period is 4a
How to find the definition range of logarithmic function
Function, y = f (x) = LG (A4 Λ x + B2 Λ x-1) / 3, the domain of definition is exactly (- 2,0), find the real numbers a, B
Let t = 2 ^ x, then 1 / 4
Given the points a (1, Y1), B (- √ 2, Y2), C (- 2, Y3) on the image of the function y = - 2x ^ 2-4x + 1, it is to compare the size relationship of Y1, Y2, Y3, and explain
It's not worth it
The function is (2x + 2) = - 4x + 1
Therefore, its axis of symmetry is: x = - 1
Therefore, among the three points, which point has the farthest abscissa from x = - 1 and which point has the largest ordinate
So, there are: Y2
Just write the x value of A.B.C (a.1 B. - √ 2 C. - 2), substitute it into y = - 2x ^ 2-4x + 1, and calculate the y value of a.b.c. it should be. I'm just imagining it
Very simple periodic function
If the image of y = f (x) is symmetric with respect to x = a, why does f (x + a) = f (A-X)? Then we deduce that f (x) = f (2a-x) is constant?
Because the image of y = f (x) is symmetric with respect to x = a
So f (x + a) = f (x-a), f (x) = - f (x)
So f (x + a) = f (A-X)
Because f (x + a) = f (x-a)
So f (x + A-A = f (x-a-a)
So f (x) = f (x-2a)
And because f (x) = - f (x)
So f (x) = f (2a-x)
Three questions about the definition and range of logarithmic function
1. If the value range of the function y = log (base 2) (true number (x ^ 2-2ax + a)) is r, then the value range of the real number a is 0 less than or equal to a less than or equal to 1
Or is a less than or equal to 0 or a greater than or equal to 1?
2. The definition field of function y = LG [x ^ 2 + (K + 2) x + 5 / 4] is r
It's K (radical 5) - 2
Or K (radical 5) - 2?
3. If f (x) = ln [(5 + k) x ^ 2 + 6x + K + 5] the domain is r, the range of K? If the domain is r, the range of K?
The second title is not quite right
The definition field of function y = LG [x ^ 2 + (K + 2) x + 5 / 4] is r
It's K (radical 5) - 2
Or - (radical 5) - 2
First question:
a> = 1 or a
