a,ve do thi cac ham so y=\(\frac{-3}{2}\)x va y=\(\frac{2}{3}\)x tren cung 1 he truc toa do
b,tren do thi ham so y=\(\frac{-3}{2}\)x lay diem A co hoanh do la 2.tren do thi ham so y=\(\frac{2}{3}\)x.Lay diem C co hoanh do la 3.do goc AOC,sau do bieu dien diem B tren mat phang toa do sao cho OABC la hinh vuong
tim giao diem cua do thi ham so y=3x-2 voi truc hoanh va truc tung
a,ve do thi ham so y=-1,5x
b,biet rang diem M(a,-3) thuoc do thi ham so tren .Tim gia tri cua a
choham so y = ax
a ) xac dinh he so a biet do thi cua ham so di qua A ( 2;3)
b ) ve do thi cua ham so voi a vua tim duoc
c) diem M ( 1005,2010) co thuoc do thi ham so vua tim duoc o tren khong ? Vi sao
Biet diem O,A thuoc do thi ham so y=1/2x .Tim toa do M(2,m) de 3 diem O,A,M thang hang
Cho ham so y = (m-1)x
A. Tim m de do thi ham so tren di qua diem M(-1;2)
B.Voi m tim duoc o cau a. Viet cong thuc ham so tren va ve do thi ham so
cho ham so y=(2m 1)x( voi m khong bang -1/2)
a) tim m de do thiham so di qua diem M (2;-1)
b) Ve do thi ham so voi m vua tim duoc o cau a
Cho biet diem A(m; 2-m) thuoc do thi cua ham so y=2x-1.hay tim m
cho hàm số y=f(x)=3x-7.Tinh (-1),f(0). Diem M (2;-1) co thuoc do thi ham so khong vi sao
