六年级上数学作业本

函数y=x^-4x+2在[0,m]上有最大值2,最小值-2,求m的范围 函数y=x^2-4x+3在区间[0,3]上的最大值为M,最小值为m,则M-m=___ 函数f(x)=-2x2+4x-1,x属于[0,3]的最小值为m,最大值为M,求M-m 函数f(x)=-2x^2+4x-1,x∈[0,3]的最小值为m,最大值为M,求M-m的值. 请问怎么写,要有过程算式 怎么写? 若函数f(x)在在反函数且函数f(x)图象在点(x,f(x))处的切线方程为2x-y+1=0,则反函数的图像在点(f(x),x)在在…存在… 北京的古建筑有哪些 北京拆除的古建筑都有哪些?尽量全些 已知函数f(x)=Asin(ωx+φ,x∈R,A>0,ω>0,0 Passport has been received from the consular section,and is currently being processed for deliver我是f1面签的,拿到了小粉条,签证官说要check,但是我是6月10号签的啊,这也太快了吧,不会给我拒签了吧, (Mr.Smith's passport) has been issued括号里面的是什么关系啊?不是主谓,是. (-a+b+c)(a+b+c) 用平方差公式 是at the beginning of 还是at beginning of那"at the start of" or "at start of" 我记得老师好象说有一个无the啊 用the beginning of造句 北京古建筑还有多少了 已知2的x次方等于3 3的x次方等于7 求12的x次方的值 已知圆O1:X`2+Y`2+2X+6Y+9=0和圆O2：X`2+Y`2-6+2Y+1=0,求圆O1和圆O2的公切线方程写下具体过程 Processed passport has been despatched through EMS 06 Aug 2008翻译..
