选项 B,y = -x 是减函数。选项 C,y = eˣ 是增函数,其反函数是 y = ln x,也是增函数。选项 D,y = log₂x 是增函数,但题干要求函数和反函数都是增函数,y = log₂x 的反函数是指数函数 y = 2ˣ,在定义域上是增函数。反馈 收藏 ...
There is an inverse if the function is one-to-one or restrictions imposed to give this state of affairs. However, the function y = sin x gives many values of x for the same value of y. To obtain an inverse we have to restrict the domain of the function to −π/2 to +π/2. ...
We call this an exact representation. This enables us to calculate the values of the function arbitrarily exactly, without roundoff errors. As an application we develop a procedure to transfer an exact representation of an increasing function into an exact representation of the corresponding inverse ...
Answer to: If the slope of a strictly increasing function at the point (a, b) is 6, what is the slope of the inverse of the function at the point...
Answer to: Suppose that y = f(x) = x^2 - 4x + 4. Then on any interval where the inverse function y = f - 1(x) exists, the derivative of y = f -...
The simplest choice for the surface normalized autocorrelation is a Gaussian function of prescribed correlation length L > 0: (2.A.1)ρ(τ)=exp(−τ2L2)⋅ Using also Equation (A.2.2), it turns out that this choice implies an inverse Gaussian shape for the structure function, the power...
Thus every Ck-di?eomorphism gives rise to a “local change of coordinates”. 4.2 The Implicit Function Theorem Next we deduce the implicit function theorem from the inverse function theorem. Theorem 4.3 (Implicit Function Theorem). Consider C1-map F : U → Rm where U is an open set in ...
Because ΔD is an increasing function of m,ΔD is always positive. Therefore, the separation of a triangle is always preferred when there is no shared node. Similarly, if s = 1, $${\rm{\Delta }}D=\frac{1}{M}\frac{\mathrm{(4}n-\mathrm{2)}{m}^{2}-\mathrm{(8}{n}^{...
moves by the Department and the Ranch. The Department apparently offered several ways to control the spread of CWD that did not involve the more drastic depopulation, but each time the Ranch said no. But this approach changed when the Department alleged that the mortality rate was increasing....
