【金版新学案】高一数学人教A版必修一练习:1.3.1.2函数的最大值、最小值(含答案解析)

(本栏目内容,在学生用书中以独立形式分册装订!)一、选择题 (每题 5分,共 20 分)1.以下函数在 [1,4] 上最大值为 3的是()1A. y=x+2 B . y= 3x- 2C. y= x2D. y= 1- x分析:B、 C 在 [1,4] 上均为增函数, A 、 D 在 [1,4] 上均为减函数,代入端点值,即可求得最值,应选 A.答案:Ax+ 7x∈ [ -1,,2.函数 f( x)=则 f(x)的最大值、最小值分别为 ()2x+ 6x∈ [1, 2],A. 10,6 B .10,8C. 8,6D.以上都不对分析:当- 1≤x<1 时, 6≤x+7<8 ,当 1≤x≤2时, 8≤2x+6≤10.∴f(x)min= f(- 1)= 6,f(x)max= f(2)= 10.应选 A.答案:A3.已知函数f(x)=- x2+ 4x+ a,x∈ [0,1] ,若 f(x) 有最小值- 2,则 f(x)的最大值为 () A.- 1 B .0C. 1D. 2分析:∵ f(x)=- (x2-4x+ 4)+ a+4=- (x- 2)2+ 4+ a,∴函数 f(x)图象的对称轴为x= 2.∴f(x)在 [0,1] 上单一递加.又∵ f(x)min=- 2,∴ f(0)=- 2,即 a=- 2.∴f(x)max= f(1) =- 1+ 4- 2= 1.答案:C4.当 0≤x≤2时, a<- x2+2x 恒建立,则实数 a 的取值范围是 ()A. (-∞, 1] B .( -∞, 0]C. ( -∞, 0)D. (0,+∞)分析:令 f(x)=- x2+ 2x,则 f(x)=- x2+ 2x=- ( x-1)2+1.又∵ x∈ [0,2] ,∴ f( x)min= f(0) = f(2)= 0.∴ a<0.答案:C二、填空题 (每题 5分,共15 分)1在 [2,3] 上的最小值为 ________.5.函数 y=x-1分析:作出图象可知y=1在[2,3]上是减函数, y min=113- 1= . x- 12答案:126.已知函数 f(x) = x2- 6x+ 8,x∈ [1, a],而且 f(x)的最小值为 f(a),则实数 a 的取值范围是 ________.分析:如右图可知 f(x)在 [1, a]内是单一递减的,又∵ f(x)的单一递减区间为 (-∞,3] ,∴ 1<a≤3.答案:(1,3]7.关于函数 f(x)= x2+ 2x,在使 f(x) ≥M 建立的全部实数M 中,我们把 M 的最大值 M max =- 1 叫做函数 f(x)= x2+ 2x 的下确界,则关于 a∈R,且 a≠0,a2- 4a+ 6 的下确界为 ________.分析:a2- 4a+ 6= (a- 2)2+ 2≥2,2则 a - 4a+ 6 的下确界为 2.三、解答题 (每题 10 分,共 20 分 )2x+ 18.已知函数f(x)=x+1 .(1)用定义证明函数在区间[1,+∞)上是增函数;(2)求该函数在区间[2,4] 上的最大值与最小值.2x1+ 12x2+1分析: (1)证明:任取x1, x2∈ [1,+∞),且 x1<x2,则 f(x1)- f( x2)=x1+1-x2+1=x1- x2.x1+x2+∵1≤x1<x2,∴ x1- x2<0, (x1+ 1)(x2+ 1)>0,∴f(x1) - f(x2)<0 ,即 f(x1)<f(x2),∴函数 f(x)在 [1,+∞)上是增函数.(2)由 (1)知函数 f(x) 在区间 [2,4] 上是增函数,∴f(x)max= f(4) =2×4+1=9,4+1 52×2+ 15f(x)min= f(2)=2+1 =3.9.有甲、乙两种商品,经营销售这两种商品所能获取的收益挨次是P(万元 )和 Q(万元 ),x3它们与投入资本x(万元 )的关系有经验公式:P=5, Q=5x.今有 3万元资本投入经营甲、乙两种商品,为获取最大收益,对甲、乙两种商品的资本投入分别应为多少?能获取的最大收益是多少?分析:设对甲种商品投资 x 万元,则对乙种商品投资(3- x)万元,总收益为y 万元,依据题意得 y=1x+33- x(0 ≤x≤ 3).55令 3- x= t,则 x= 3- t2,0≤t≤ 3.12313221因此 y=5(3- t ) +5t =-5t-2+20,t∈ [0, 3].当 t=3时, y max=21,此时 x= 0.75,3- x= 2.25. 220由此可知,为获取最大收益,对甲、乙两种商品的资本投入分别为0.75 万元和 2.25 万元,获取的最大收益为 1.05 万元.。

Evaluation Only. Created with Aspose.Words. Copyright 2003-2016 Aspose Pty Ltd.(本栏目内容,在学生用书中以活页形式分册装订!)1.(2011·海南省四校联考)依次填入下面文字中横线处的词语,最恰当的一组是( )有位作家说,要想使自己生活的扁舟轻驶,务必要让它的________仅限于必不可少之物,不然轻则________无以进,重则可能压沉自己的生活之舟。
道理很明白,什么都舍不得撒手,往往________什么都不得不________。
A.装载徜徉致使割爱B.承载徘徊导致舍弃C.装载徘徊致使舍弃D.承载徜徉导致割爱解析:“承载”义为“托着物体,承受它的重量”,而“装载”是“用运输工具装”的意思,第一空填“承载”较妥。
“徜徉”义为“闲游、安闲自在地步行”,与句意矛盾,故只能用“徘徊”。
“割爱”指“放弃心爱的东西”,与原句中“什么都”不吻合。
答案: B2.(2011·海南五校联考)依次填入下列各句中横线处的词语,最恰当的一组是( )①为表达对青海玉树地震遇难同胞的深切哀悼,国务院决定,4月21日举行全国哀悼活动,全国和驻外使领馆下半旗________。
②2010书香中国,以“今天,你读了吗”为口号倡导大众阅读,讲述中国人的阅读故事,通过各个层面________中国人今天的阅读风貌。
③中国传统节日________着丰富的文化内涵,是弘扬中华民族精神的重要文化载体,传承传统节日文化有利于增强民族凝聚力。
A.致哀展示蕴蓄B.志哀显示蕴蓄C.致哀显示蕴含D.志哀展示蕴含解析:“致哀”,对死者表示哀悼;“志哀”,用某种方式表示哀悼。
“显示”,显现,表示;“展示”,呈现出来让大家看。
“蕴蓄”,积蓄或包含在里面而未表露出来;“蕴含”,包含。
对于近义词的辨析,一是弄清词语的本义,如“显示”与“展示”;二是注意词语的侧重点,如“致哀”侧重在“表达、表示”,而“志哀”则重在“用某种特定方式”;“蕴蓄”侧重“积蓄”,“蕴含”侧重“包含”。

Maive Rute suggests feeding animals a diet designed to reduce emissions.The new agricultural research group says protecting against global warming is only part of its purpose.It says the world also needs to develop better farming methods to feed growing populations in poor countries.United States Agriculture Secretary Tom Vilsack said no one single nation can fight agricultural greenhouse gas emissions and increase food production at the same time.This is why the alliance is important for combining resources and finding new ones.The United States Department of Agriculture will increase spending on farm emissions research by ninety million dollars over the next four years.The total will reach one hundred and thirty milliondollars.The U.S.D.A.will share the research with other countries in the Global Research Alliance on Agricultural Greenhouse Gases and support researchers from developing countries that belong to the alliance. Money from the Borlaug Fellowship Program will let the researchers study agricultural climate change with American scientists.Mister Vilsack said that just as climate change has no borders,there should be no borders for research.1.In Paragraph 4,Maive Rute recommends________.A.increasing food productionB.changing cattle digestive systemsC.developing better farming methodsD.giving animals the food meant to produce fewer emissions2.The underlined word “alliance” in Paragraph 6 probably means________.A.action or state being joined togetherB.an agreement signed between countriesC.a program or project set up for a researchD.an organization formed for different goals3.How much has the U.S.D.A.spent on farm emissions research so far?A.130 million dollars. B.220 million dollars.C.40 million dollars.
