Cho ham so bac nhat y=mx+1
a, Tim mde ham so nghich bien ? Ve do thi ham so voi m=2
b, Tim m de do thi ham so qua M (3;2) . Ve do thi ham so voi m tim duoc
c , Chung to do thi ham so luon qua 1 diem co dinh voi moi gia tri cua m
xet ham so y=mx+2-m (1) a) ve do thi cua ham so ung voi m=-2;m=3 tren 1 mat phang toa do. tim toa do giao diem cua 2 do thi. b) chung minh rang khi m lay cac gia tri khac nhau thi do thi cua ham so (1) van luon di qua 1 diem co dinh thuoc paraboly=2x^2
xet ham so y=mx+2-m (1)
a) ve do thi cua ham so ung voi m=-2;m=3 tren 1 mat phang toa do. tim toa do giao diem cua 2 do thi.
b) chung minh rang khi m lay cac gia tri khac nhau thi do thi cua ham so (1) van luon di qua 1 diem co dinh thuoc paraboly=2x^2
tim gia tri cua m de do thi cua hai ham so y=(x^2+4)*x+7 va y=(3m+2)*x+8
Bai 2:(1,0 diem) Cho ham so y = - 2x + 3 (d)
a) Ve do thi (d) cua ham so tren.
b) Tim m de do thi ham so y = (m+ 1)x - 3 song song voi do thi ham so y = - 2x + 3.
help!!!!!
cho ham so y =(2m-4)x-1. Tim m de do thi ham so dong quy voi hai duong thang y = -x+1 va y=2x-5
Gia tri cua m la
xac dinh gia tri cua m de do thi ham so y=2n[x+1] son song voi da' [d] : y=2x-3
Ve do do thi cua cac ham so Y = x + 1 va Y = -x+3 tren cung mot mat phang toa do.
cho ham so y=1/2x va y = -1/2x a) ve tren cung mat phang toa do do thi cua 2 ham so tren b) ham so nao dong bien ham so nao nghich bien
