问题 解答题

已知函数f(x)=|3x-6|-|x-4|.

(1)作出函数y=f(x)的图象;

(2)解不等式|3x-6|-|x-4|>2x.

答案

(1)见解析    (2) {x|x<}

(1)f(x)=|3x-6|-|x-4|

=

正确画出图象.

(2)在图中画出y=2x的图象如图,

注意到直线y=2x与射线y=2-2x(x<2)交于(,1),线段y=4x-10(2≤x≤4)在直线y=2x下方,射线y=2x-2(x>4)在直线y=2x下方且与直线y=2x平行,故由图象可知不等式|3x-6|-|x-4|>2x的解集为{x|x<}.

瓶庵小传

魏禧

吴门枫江之市,有君子焉,人皆称曰瓶庵。或曰守口如瓶,取谨言之义。或曰瓶窄口而广腹,善容物者也。

瓶庵幼失怙废学,长自力于学,好文墨士,于贤人隐君子尤尊敬之。朋友之穷老,无所归者,曰:“于我乎养生送死。”于是士君子皆贤瓶庵。人有急难之日,好行其德。尝僦小舟,问舟子日:“几何钱?”曰数若干,瓶庵曰:“米贵甚,如是,汝安得自活?”乃增其值。故负贩人亦曰瓶庵盛德长者。吴门高士徐枋,难衣食,瓶庵尝馈遗之,枋不辞。

瓶庵年六十,家人将觞客,瓶庵曰:“吾将归故乡,以是费为祖宗祠墓费。吾六十,善病,不于此时一拜先陇①,更何待耶?”于是去,倡建始祖祠,修五世以上墓,拜故旧之陇而酹之,不令其子孙知。事竣,力疾游黄山而后返。里有事,尝就瓶庵平曲直,白徒②悍卒皆服之。或曰:“瓶庵之父,往侨维扬,会逆阉魏忠贤用事,有假其威虐人者,君以布衣叩阍。抗疏,既危而免。”瓶庵殊多父风也,父尝刲股以疗亲痛,瓶庵父病亦刲股。瓶庵之妹死,有遗子女,并婚嫁之如己出。其孝友如此。于是远近士至吴门者,皆欲争识瓶庵矣。

[注]①先陇:祖先陇地,祖墓。②白徒:本指无军籍临时征集的壮丁。此处指散漫无管束的人。③叩阍(hūn):向朝廷进言。
