周周测(八)_____月_____日建议用时:45分钟(考查范围:19.2.1-19.2.2.2)1.下列函数中,是正比例函数的是(A)A.y=-8xB.y=-8xC.y=5x2+6D.y=-0.5x-12.下列说法中不正确的是(D)A.一次函数不一定是正比例函数B.不是一次函数就一定不是正比例函数C.正比例函数是特殊的一次函数D.不是正比例函数就一定不是一次函数3.(2023·长沙中考)下列一次函数中,y随x的增大而减小的函数是 (D)A.y=2x+1B.y=x-4C.y=2xD.y=-x+14.等腰三角形周长为20 cm,底边长y cm与腰长x cm之间的函数关系是(B)A.y=20-2xB.y=20-2x(5<x<10)C.y=10-0.5xD.y=10-0.5x(10<x<20)5.(2023·陕西中考)在同一平面直角坐标系中,函数y=ax和y=x+a(a为常数,a<0)的图象可能是(D)6.关于函数y=2x-4的图象,下列结论正确的是(C)A.必经过点(1,2)B.与x轴的交点坐标为(0,-4)C.过第一、三、四象限D .可由函数y =-2x 的图象平移得到7.(2023·临沂中考)对于某个一次函数y =kx +b (k ≠0),根据两位同学的对话得出的结论,错误的是(C)A .k >0B .kb <0C .k +b >0D .k =-12b8.已知正比例函数y =kx 的图象经过点A (-1,7),则正比例函数的解析式为 y =-7x . 9.已知一次函数y =kx -1,请你补充一个条件 k <0 ,使函数图象经过第二、三、四象限. 10.已知点A (x 1,y 1),点B (x 2,y 2)是一次函数y =2x -m 图象上的两个点,若x 1>x 2,则y 1-y 2 > 0.(填“>”“<”或“=”)11.(2023·贵阳南明区模拟)把直线y =2x -1向左平移1个单位长度,再向上平移2个单位长度,则平移后所得直线的解析式为 y =2x +3 .12.为了增强公民的节水意识,某市制定了如下用水收费标准:每户每月的用水不超过10吨时,水价为每吨1.2元,超过10吨时,超过的部分按每吨1.8元收费,该市某户居民5月份用水x 吨(x >10),应交水费y 元,则y 关于x 的函数关系式是 y =1.8x -6(x >10) .13.已知正比例函数y =kx (k 是常数,k ≠0),当-3≤x ≤1时,对应的y 值的取值范围是-1≤y ≤13,且y 随x 的减小而减小,求k 的值.【解析】∵y 随x 的减小而减小,∴k >0,则有x =-3时,y =-1;x =1时,y =13,所以点(-3,-1),(1,13)在函数y =kx (k 是常数,k ≠0)的图象上,所以-1= k ·(-3), 所以k =13.14.已知一次函数y =mx -(m -2). (1)若图象过点(0,3),则m 是多少?(2)若它的图象经过第一、二、四象限,则m 的取值范围是多少? (3)若直线不经过第四象限,则m 的取值范围是多少?【解析】(1)∵一次函数y =mx -(m -2)的图象过点(0,3),∴3=-(m -2),解得m =-1; (2)∵一次函数y =mx -(m -2)的图象经过第一、二、四象限,∴{m<0-(m-2)>0,解得m<0,即m的取值范围是m<0;(3)∵一次函数y=mx-(m-2)的图象不经过第四象限,∴{m>0-(m-2)≥0,解得0<m≤2,即m的取值范围是0<m≤2.15.已知一次函数y=2x+4.(1)在如图所示的平面直角坐标系中,画出该函数的图象;(2)求图象与x轴的交点A的坐标,与y轴交点B的坐标;(3)在(2)的条件下,求出△AOB的面积.【解析】见全解全析16.小明同学根据函数的学习经验,对函数y=|x-2|+|x+4|进行了探究,下面是他的探究过程:(1)已知当x=-4时,|x+4|=0;当x=2时,|x-2|=0,化简:①当x<-4时,y=_____ ;②当-4≤x≤2时,y=_____ ;③当x>2时,y=_____ .(2)在平面直角坐标系中画出y=|x-2|+|x+4|的图象,根据图象写出该函数的一条性质:_________________________ .(3)根据上面的探究解决下面问题:已知P(a,0)是x轴上一动点,A(-4,6),B(2,6),则AP+BP的最小值是_____ .【解析】(1)∵x=-4时,|x+4|=0;x=2时,|x-2|=0,①当x<-4时,y=2-x-x-4=-2-2x;②当-4≤x≤2时,y=2-x+x+4=6;③当x>2时,y=x-2+x+4=2x+2.答案:①-2-2x;②6;③2x+2。
