The monotone decreasing interval of function y = − 23x3 + (a + 1a) x2 − 2x + 4 (where a < - 1) is ()
A. (−∞，1a)、（a，+∞）B. （-∞，a）、(1a，+∞)C. (1a，a)D. (a，1a)
The derivative of the function y = - 23x3 + (a + 1a) x2 − 2x + 4 is y ′ = - 2x2 + 2 (a + 1a) x − 2, let y ′ < 0, then, (x-a) (x-1a) > 0, ∵ a < - 1, ∵ x > 1A, or the monotone decreasing interval of the function x < A is (- ∞, a), and (1a, + ∞), so B is selected
Given the function f (x) = 2x + 1 / x, judge whether f (x) is an increasing function or a decreasing function on (1, + infinity), and prove it
It is proved that: (1) when x = 2, f (2) = 1 / 6 of 2 * 2 + 2, that is, 1 / 6; when x = 3, f (3) = 1 / 9 of 2 * 3 + 3, that is, 1 / 9; therefore, f (x) is a decreasing function at (1, + infinity)
When a number moves six unit lengths to the right on the number axis, the corresponding point of its opposite number is obtained, then the opposite number of the number is ()
A. -3B. 3C. 6D. -6
After the point corresponding to a number on the number axis moves 6 units to the right, we get its opposite number, that is, the distance between the point corresponding to this number and its opposite number on the number axis is 6 unit length. Moreover, the distance between these two points and the origin is equal, and this point is on the left side of the origin, so this number is - 3. So we choose a

The monotone decreasing interval of function f (x) = 2x square - 3x square + 10 is
f(x)=2(x-3/4)²-71/8
The opening is symmetrical on the axis X = 3 / 4
So the minus interval is (- ∞, 3 / 4)
It is proved that the function f (x) = (2x-1) / (x + 1) is a decreasing function on [1, + infinity]
How can f (x) = 1 be a decreasing function when x = 1? If the title is changed to prove that this function is an increasing function, the proof is as follows: let X1 > x2 ≥ 1F (x1) - f (x2) = (2x1-1) / (x1 + 1) - (2x2-1) / (x2 + 1) = (2x1x2 + 2x1-x2 -)
Jg_ In the answer of Zhou,
1 / (1 + x) decreases with the increase of X, but f (x) = 2-3 / (x + 1), so the function is increasing from 1 to infinity.
f(x)=(2x-1)/(x+1)
=(2x+2-3)/(x+1)
=2-3/(x+1)
When x > = 1, 1 + x > = 2, 1 / (1 + x)
