No, it's a phrase: one piece
For example: (a piece of bread.)
Given the function f (x) = x-2ax-1, if x belongs to [0,2], f (x) is less than or equal to 2 / 3a, the value range of real number a is obtained
f(x)=x²-2ax-1=(x-a)²-a²-1
When a ≤ 1
The maximum of F (x) on [0,2] is f (2) = 3-4A ≤ 2 / 3a
a≥9/14
9/14≤a≤1
a> 1:00
The maximum of F (x) on [0,2] is f (0) = - 1 ≤ 2 / 3a
A>1
a≥9/14
F (x) = lnx-ln2, X ≥ 2, find the inverse function of F (x)
Y = LNX / 2, X ≥ 2, X / 2 ≥ 1, so y ≥ 0
The solution is x, X / 2 = e ^ y, x = 2E ^ y, (Y ≥ 0)
Commutative x, y, inverse function y = 2E ^ x, (x ≥ 0)
F negative power (x) = e ^ (LN2 + x)
There are three points a, B and C on the number axis. Given that point a represents 1, point B represents - 2 and point C represents - 7, how to move the two points in a, B and C so that the numbers represented by the three points are the same? How many ways?
There are three moving methods: first, move point B 3 units to the right and point C 8 units to the right. Second, move point B and point a 5 units and 8 units to the left respectively. Third, move point C 5 units to the right and point a 3 units to the left
It is known that the parabola y = mx2-2 (3m-1) x + 9m-1, no matter what value x takes, the value of function y is non negative, and the value range of M is obtained
∵ parabola y = mx2-2 (3m-1) x + 9m-1, no matter what the value of X is, the value of function y is non negative, ∵ the opening direction of parabola is upward, and there is an intersection or no intersection with X axis, ∵ m > 0, and △ ≤ 0, that is, 4 (3m-1) 2-4m (9m-1) ≤ 0, and M > 0, the solution is m ≥ 15
The monotone increasing interval of function f (x) = Log1 / 2 (x * 2-4) is?
u=x^2-4>0,x2,
X 2, u single increase,
Log1 / 2 (U) single minus,
According to the monotonicity judgment rule of composite function,
The increasing interval is X
As shown in the figure, there are three points a, B and C on the number axis. How to move the two points in ABC so that the numbers represented by the three points are the same?
A = - 5 B = - 2 C = 1
Method 1: a moves 3 units [1 - (- 2) = 3] left to C, B moves 5 units [3 - (- 2) = 5] left to C, then the number of three points is the same; method 2: B moves 2 units [3-1 = 2] left to a, C moves 3 units [1 - (- 2) = 3] right to a, then the number of three points is the same; method 3: a moves 2 units [3-1 = 2] right to B, C moves 5 units [3 - (- 2) = 5] right to B, then the number of three points is the same, The number of the three points is the same;
Mathematical answer group answers for you
First, compare the size of the three numbers. When the number is larger, move it to the right;
When it is expressed on a small number, it moves to the left. The number of moves is the distance between them (large decimal).
For example, if both denote - 2,
If it is shifted to the right, it is equal to (- 3), (- 5)
C shifted to the left (- 2 < 1), 3 units (1 minus - 2 equals 3).
It can also be expressed as - 5, 1. (do it yourself)
