Who has the answer to the last question of the passage in unit 2 of the sixth grade Chinese exercise book

Wrote the author's rich imagination and childlike innocence

Is there any difference between the great God of Mathematics (X & # 178;) ^ (3 / 2) and X & # 179?
For (X & # 178;) ^ (3 / 2) and X & # 179; respectively, why are the results different?

If we consider real numbers, the former is square, so the values are all positive, while the latter has negative. Integral is the area of the graph composed of curve and abscissa. The former only has integral above abscissa, so the integral is positive, while the latter has positive and negative, so the integral is zero

The known parabola y = 4x square-11x-3 and the x-axis Y-axis focus coordinates

When x = 0, y = - 3, so the coordinates of its intersection with the Y axis are (0, - 3)
When y = 0
4x^2-11x-3=0
(4x+1)(x-3)=0
x=-1/4 x=3
So the coordinates of its intersection with the X axis are (- 1 / 4,0) and (3,0)

Let a (a + 2,3-2a) shift point a three units to the right and then down
Translate 2 units to get point a ', where point a' is on the straight line x = - 2, and calculate the coordinates of point a

If a moves 3 units to the right, then x = a + 5 = - 2 is added to the abscissa, and a = - 7 is obtained. If a moves down by 2 units, y = 1-2a is subtracted from the ordinate, and y = 15 is obtained. Therefore, the coordinate of a is (- 5,17)

If f (x) SiNx is an odd function with period, then f (x) can be

If f (x) SiNx is an odd function with period π, then f (x) can be ()
A.sinx B.cosx C.sin2x D.cos2x
Choose B
∵ cosxsinx = (1 / 2) sin2x, is an odd function with period π,
None of the other three options will work

It is proved that the function is a decreasing function
It is proved that f (x) = x ^ 2 + 1 is a decreasing function on (- ∞, 0)~

Let X1 < x2 < 0
f(x1)-f(x2)=(x1^2+1)-(x2^2+1)
=x1^2-x2^2
=(x1-x2)(x1+x2)
x1-x2＜0,x1+x2＜0
Therefore, f (x1) - f (x2) > 0
f(x1)＞f(x2)
So, f (x) is a decreasing function on (- infinity, 0)

It is known that the sum of the intercept of the line 2x-3y + 6 = 0 on the X axis and the intercept on the Y axis

Let x = 0, y = 2; that is, the intercept of the line 2x-3y + 6 = 0 on the Y axis is 2,
Let y = 0, x = - 3, that is, the intercept of the line 2x-3y + 6 = 0 on the X axis is - 3,
So the sum of intercept is - 1
