Properties of power function Three basic properties of power function~```` Well, I just want a simple narration`
Properties of power function y = xn
There are definitions in (0, + ∞), and the images are all over (1,1)
When n > 0, the images pass through the origin and are increasing functions on (0, + ∞);
When n
What are the properties of power function?
Open classification of power function: mathematics, function, the general form of power function is y = x ^ a
On the properties of power function
If the equation x & sup2; - 2mx + 4x + 2m & sup2; - 4M-2 = 0 of X has real roots, find the maximum of the product of two
There is no maximum, the minimum is - 4
