填空一题 选择四题 4题选择填空 选择填空的第4题. 这四题填空和选择怎么做 f(x)是定义在R上的奇函数,且y=F(x)的图像关于直线x=1/2对称,则f(1)+f(2)+f(3)+f(4)+f(5)等于多少 已知y=f(x)是定义在R上的函数,其图像关于x=2对称,当x大于等于零时,f(x)=5x+3,求当x小于2时f(x)函数 ‘我自己的’英文是什么?如题 设函数y=f(x)的图象关于直线x=1对称,在x≤1时,f(x)=(x+1)2-1,则x>1时f(x)等于( )A f(x)=(x+3)2-1 B f(x)=(x-3)2-1C f(x)=(x-3)2+1 D f(x)=(x-1)2-1 填空第九题 第九题,填空 第九题,填空, 第九题,填空. 选出括号内意思相同或相近的选项1.He'll go there (by plane) next week.A.by the air B.on plane C.on a plane .D.by a plane 2.We all know Africa (is out of) water.A.ia in lack of B.is full of C.run out D.use out 3.The girl (has a sweet 在同一平面直角坐标系中,画出下列函数图像(1)y=x与y=x+4(2)y=-2x与=-1/2x+5 选出与括号部分意思相同或相近的选项Classes (begin) at nine o'clock(1)start (2)are over (3)have lessons (4)finishIt's (five to five) now(1)5:05 (2)5:15 (3)5:45 (4)4:55The workers works (48 bours)(1)a day (2)tow days (3)three days (4)fo 在同一平面直角坐标系中,画出函数y=2x+4的图像,指出每个函数中当x增大时y如何变化 选出在括号内意思相近或相同的选项I like the mooncake with nuts inside.A:on itB:in itC:withD:round 英语填空9题都做 在同一平面直角坐标系中,画出函数y=二分之五x=1和y=5x+17的图像并结合图像比较这两个函数值的大小关系 又是英语选择、、、、还需要选项解释、答案我有的、、、谢谢了、、、1.I often sleep late and ___________ breakfast.A.skipB.skip overC.skip acrossD.skip round2.I've heard that McDonald's is losing market _________ in the St 下面的选项选什么 I don' t think you two know each other,__________ [ A ] do you [ B ] don' t you [ C ]do I [ D ] don't I 一道英语选择 (请解释每个选项的区别)My chest _____ when I make a deep breath,doctor.A harms B wounds C hurts D injures 英语选择.写为什么选这个答案.每个选项意思 在同一平面直角坐标系中,画出函数y=x+1,y=x-1,y=-x+1,y=-x-1的图像,这四条 在同一平面直角坐标系中,分别画出y=x、y=x-2、y=x+2三个函数的图像,并说出它们有何位置关系 在平面直角坐标系中分别画出函数Y=X与Y=1/X的图像,用着两个图像说明何时X比1/X大,何时X比1/X小? 填空第一题 下列图形都是二次函数y=ax平方+bx+a平方-1的图象,若b>0,则a的直等于? 解释下面几句英语?括号里面的.Publish Date:April 1,2007【WOMAN WILL NEVER BE GREEK ENOUGH FOR HUSBAND'S FAMILY】DEAR ABBY:I married a Greek man whose family never accepted me.Being young and naive,I tried everything to fit in,converting 举个例子,ripe a.熟的 成熟的;(for)时机成熟的这里的for 用简单的英语解释下列句子:(带括号的)1.How did the thief (go into) the house?2.He says that he (isn't) young (any longer)3.Please (take) your bag (away from) the seat.4.(Why don't you) go to the cinema tonight5.The boy was (so) ex 根据首写字母填空第一题
