D.【答案】C【解析】A选项在上是增函数;B选项在是减函数,在是增函数;C选项在是减函数;D选项在是减函数,在是增函数;故选C.【点睛】对于二次函数判定单调区间通常要先化成形式再判定.当时,单调递减区间是,单调递减区间是;时,单调递减区间是,单调递减区间是.2. 函数在区间[-2,+∞)上是增函数,在区间(-∞,-2)上是减函数,则等于()A. -7B. 1C. 17D. 25【答案】D【解析】试题分析:由题意得,对称轴为,得,得f(x)=4x2+16x+5,所以f(1),选D.考点:二次函数对称轴、函数单调性.3. 函数的递增区间依次是( )A. B.C. D.【答案】C【解析】函数,该函数的单调递增区间为;本题选择C选项.4. 已知函数在区间上是减函数,则实数的取值范围是()A. B. C. D.【答案】A【解析】试题分析:∵,其对称轴为:,∵函数在上是减函数,∴,∴,故选A.考点:二次函数的性质.二、填空题(5分×4=20分,将答案填在答题卡中相应位置)5. 函数在区间[1,5]上的最大值为_____,最小值为_____.【答案】 (1). 3 (2).【解析】在是减函数,所以最大值为,最小值为.6. 函数的奇偶性为________(填奇函数或偶函数).【答案】奇函数【解析】由已知得的定义域为即,则其定义域关于原点对称,,所以是奇函数.【点睛】利用定义判定函数的奇偶性的一般步骤为:1、判断函数的定义是否根据原点对称;2、若不对称则为非奇非偶函数;3、若对称再进一步判断与的关系,若则为偶函数,若则为奇函数.7. 若是偶函数,则=_________.【答案】0【解析】,其为偶函数,所以解得 .8. 已知是偶函数,是奇函数,若,则的解析式为_______.【答案】三、解答题(10分)9. 已知函数,∈[0,2],用定义证明函数的单调性,并求函数的最大值和最小值.【答案】证明见解析;最小值是,最大值是【解析】试题分析:取其定义域内的值,分别代入再作差得,即可证明f(x)在区间上是增函数;根据增函数的图象可知最小值点是,最大值是.试题解析:解:设,则.由,得,所以,即,故f(x)在区间上是增函数.因此,函数在区间[0,2]的左端点取得最小值,右端点取得最大值,即最小值是,最大值是.【点睛】定义法判定函数的单调性的步骤如下:1、在定义域内取值;2、作差;3、定号;4、判断.。
