Your request is too far from the mark. I'm tired to death and have no marks. It's better for me to give you a tense and write a sentence, and then teach you the sentence pattern reform. Affirmative sentences, negative sentences and interrogative sentences all have certain rules to follow
There are five sentences in the present tense, the past tense, the present continuous tense and the future tense,
I do my home every day. I go to school on foot.He can swim.There Are seven days in a week. I like watching TV yesterday.Last week I read an English book.He w...
Write an English composition in the present tense, the past tense and the present continuous tense
The present tense, the past tense and the present progressive tense are three tenses in English composition
Present tense

When there are no elements in the set composed of the solutions of the equation AX's square + 2x + 1, what is the value range of the real number a?
When the solution of the set of equations is composed of 2x + 0, ax = 1
Let's know the square + 2x + 1 = 0 of the equation AX has no solution
When a = 0, the equation is 2x + 1 = 0, and the solution is x = - 1 / 2,
When a ≠ 0, the equation is quadratic, and Δ < 0
That is, 2 ^ 2-4a < 0
The solution is a > 1
A is greater than 1
Question: Well, it was given by the teacher, and I don't think it's right
Given that the function y = f (x) satisfies f (x) = 2F (1 / x) + X, the analytic expression of F (x) is obtained
f(x)=2f(1/x)+x ①
If x is regarded as 1 / x, then
f(1/x)=2f(x)+1/x ②
F (x) = - 2 / 3x-x / 3 is obtained from the solution of (1) and (2)
Let x = one in X
Let x = 1 / x, then f (1 / x) = 2F (x) + 1 / X. if f (1 / x) is eliminated, y = - 1 / 3 (x + 2 / x)
How to express the set of points on the image of quadratic function y = x square by description method?
{(x,y)|y=x^2}
If there are two real roots (a + 2, b) in the range of (a + 2), then (a + 2) is a real number
A．(-wuqiong,4) B．(4,+wuqiong) C.(-wuqiong,-4) D .(-4,4)
Please help. How to solve, please pay attention to the answer to choose a
f(1)f(2)
If the function FX satisfies FX + 2F (1 / x) = x, then f (x)=
f(x)+2f(1/x)=x
f(1/x)+2f(x)=1/x
Solution
f(x)=2/(3x)-1/3
The set of function values of quadratic function y = x (square) - 4
Select the appropriate method to represent the following set
Using the description method, because it is a quadratic function, first determine the vertex (0, - 4)
Then y must be greater than or equal to - 4, that is {y belongs to R / y greater than or equal to 4}
Given the mapping f: a → B, where a = b = R, the corresponding rule F: y = - x2 + 2x, for the real number k ∈ B, there is no primitive image in the set a, then the value range of K is ()
A. k＞1B. k≥1C. k＜1D. k≤1
∵ y = - x2 + 2x = - (x-1) 2 + 1 ≤ 1 ∵ the value range of function is (- ∞, 1] ∵ for real number k ∈ B, there is no original image ∵ k > 1 in set a, so a is selected
