If f (x) = sin (2wx - π / 6) function y = f (x) x ∈ (m, M + π) m ∈ R, there is only one intersection point w =?

If f (x) = sin (2wx - π / 6) function y = f (x) x ∈ (m, M + π) m ∈ R, there is only one intersection point w =?


In π, there is only one intersection point with the line y = 1, that is, there must be a maximum
So f (x) period is π, so w = 1



The maximum value of the function y = 2x2 + 3x + 4 in the interval [- 1,1 / 4] is -- the minimum value is——


y=2(x+3/4)^2+23/8
When x = - 3 / 4, the minimum value of the function is 23 / 8
When x = 1 / 4, the maximum value of the function is 39 / 8



The function f (x) = ax + B, a, B ∈ R is known. When x is greater than or equal to - 1 and less than or equal to 1, the absolute value of F (x) is less than or equal to 1


-1≤x≤1
-a≤ax≤a
-a+b≤ax+b≤a+b
Then - 1 ≤ - A + B and a + B ≤ 1
From this solution, a ≤ 1-B (when B ≥ 0) and a ≤ 1 + B (when B ≤ 0) are obtained

Hope to help you



(8x-800) / (5x-980) = 8 / 3 solution equation


(8X-800)/(5X-980)=8/3
==>(X-100)/(X-196)=8/3
==>3(X-100)=8(X-196)
==>3X-300=8X-1568
==>5X=1268
==>X=253.6
6 is the root of the original equation
So the root of the original equation is x = 253.6



1.4 × 2.5-0.2x = 1.7 the whole process is necessary to solve the equation
The process should be detailed


1.4×2.5-0.2x=1.7
3.5-0.2x=1.7
The result of the transfer is as follows:
0.2x=3.5-1.7
0.2x=1.8
x=9



Solution equation (1 / x + 2) + (2x ^ 2 / x ^ 2-4) = 2


(1 / x + 2) + (2x ^ 2 / x ^ 2-4) = 2 times x ^ 2-4 = (x + 2) (X-2)
x-2+2x^2=2x^2-8
x-2=-8
x=-6



Solve the equation 2 / 3 | 2x-3 | = 4
2 / 3 2x-3 = 4 exercise book questions!


2 / 3 | 2x-3 | = 4
|2x-3 | = 4 △ 2 / 3
|2x-3|=6
2x-3 = - 6 or 2x-3 = 6
X = - 1.5 or x = 4.5



27x-512 = 0, find the cube of X-2 = - 64, find the value of X
If the cube root of 2 is known to be 1.260, then the cube root of 2000 is 0.002?
Finding X by cube of 27x-152 = 0


The cube root of 2000 = 1000 × 2 = 10 × 1.260 = 12.60
002 = 0.001 × 2 = 0.1 × 1.260 = 0.1260
