Given f(x) = 3x2 – 4x, find the difference quotient Assume h + 0 and simplify your h answer. Step 2: Replace f(x + h) with the subsequent polynomial derived from substituting (x + h) into f(x); and replace f(x) with it's algebraic representation 4x^2 Step 3 : Simplify the numerator of the given algebraic expression for f(x + h) - f(x)
高一二次函数二次函数fx满足f(x+1)-fx=2x且f0=1(1)求fx解析式(2)当x属于-1,1的闭区间时,不等式. 1年前 1个回答 概率论与数理统计(第三章第2节) - MBA智库文档 f (x, y) ≠ fX (x) fY ( y) 或者找出 f (x, y) 的一个连续点 (x0, y0), 使得 f (x0, y0) ≠ fX (x0) fY ( y0) 分析上述结果, 我们得到 判断随机变量独立性的一般步骤 联合分布 边缘分布 判断是否独立 例1. 设随机变量 ( X, Y ) 具有联合概率密度 问: X、Y 是否相互独立？
We would like to show you a description here but the site won’t allow us. 已知随机变量X的概率密度为fx(x),令Y＝－2X,则Y的概率密度为 2017-10-04 已知连续型随机变量X的概率密度为fX(x)且Y=2X,则Y的概率密度fY(y)= 2017-10-13 设随机变量X和Y相互独立,它们的概率密度分别为fx(X),fy(y),则（X,Y)的概率密度为 2017-10-19 The OP posted a comment below nbubis's answer asking what to do with $\frac{\sin^2(\frac{h}{2})}{h}$. I can't comment back, (no reputation at all) so here's my contribution, multiply $\frac{h}{4}$ in the numerator and denominator. This will lead to $\frac{\sin^2(\frac{h}{2})}{(\frac{h}{2})^2}*\frac{h}{4}$.
已知函数f(x)=ax2+bx，存在正数b，使得f（x）的定义域和值域相 … 已知函数f(x)=ax2+bx，存在正数b，使得f（x）的定义域和值域相同．（1）求非零实数a的值；（2）若函数g(x)=f(x)-bx有零点，求b的最小值．-数学-魔方格
