Is "X" in quadratic function "y = a (X-H) & #" a straight line x? In other words, is the value of "X" in the quadratic function "y = a (X-H) & #" equal to the value of the straight line x?
The "X" in the quadratic function "y = a (X-H) &#" represents the value of the independent variable, not the straight line
The following statement is wrong ()
A. In the quadratic function y = 3x2, when x > 0, y increases with the increase of X. B. in the quadratic function y = - 6x2, when x = 0, y has the maximum value 0C. In the parabola y = AX2 (a ≠ 0), the larger a is, the smaller the opening of the image is, and the larger a is. D. whether a is positive or negative, the vertex of the parabola y = AX2 (a ≠ 0) must be the coordinate origin
A. In the quadratic function y = 3x2, when x ＞ 0, y increases with the increase of X, which is not in line with the meaning of the problem; B, in the quadratic function y = - 6x2, when x = 0, y has the maximum value of 0, which is not in line with the meaning of the problem; C, in the parabola y = AX2 (a ≠ 0), the larger | a | is, the smaller the image opening is, and the smaller | a | is, the larger the image opening is, which is not in line with the meaning of the problem; D, whether a is positive or negative The vertex of parabola y = AX2 (a ≠ 0) must be the origin of coordinate
When the polynomial - 5x & # 179; - (m-1) x & # 178; + (2-N) X-1 does not contain binomial and linear terms about X, the value of M, n is obtained
If there is no quadratic term, then M-1 = 0, M = 1
If there is no linear term, then 2-N = 0, n = 2

- 8. The autumn of the Three Gorges Autumn of the Three Gorges In the morning, the transparent dew is shining, and the wind in the gorge is cool, as if the orange and pomelo trees all over the mountain have a layer of white frost, fresh and clean; when the sun comes out, the dew disappears, the orange and pomelo trees are shining with sunshine, green leaves and golden fruit; the Three Gorges is a beautiful autumn At noon, the peaks are covered with gold armour, the sun is jumping on the water surface, and the Yangtze River becomes warm, like a golden scale python, rolling, whistling and rushing away. At the same time, it throws the surging and jumping brilliance to the cliffs on both sides, so the whole Canyon is rippling, and the Three Gorges is full of the warm atmosphere of autumn In the afternoon, before the sun sets, a layer of cyan fog rises early in the gorge. This makes the dusk in the gorge come early and go late. So, in the cyan transparent dusk, the reflections of the cliffs on both sides rush to the center of the river, leaving a bright sky on the river. The Yangtze River flows quietly and gently, like a bright belt Night, at last, comes. The fishing lights on the bank and the lights in the middle of the river light up one after another, together with the red halo they reflect on the water surface, making the Yangtze River seem to blink and sleepy. Only occasionally passing barges sound their sirens and carve a luminous road on the water surface. So the lights of the fishing lights, like waking up, sway gently on the water surface This is it
