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
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
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
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
cho ham so y=(2k+1).x
a/ tim k biet do thi di qua A(-1;1)
b/ ve do thi ham so nay
c/ cho B(xB;-10);C(-5;yC) thuoc do thi tim xB, yC
cho hai ham so y=f(x)=|2x| va y=g(x)=3
a)ve tren cung mot he truc toa do Oxy do thi cua hai ham so do
b)dung do thi ham so tim cac gia tri cua x sao cho |2x|<3
Cho ham so y= ax Do thi ham di qua diem A(1;-2) a.Xac dinh he so a di qua A (1;-2) b.ve do thi ham so va a vua tim duoc
cho ham so y=f(x)=2x va y=g(x)=18/x . khong ve do thi ham so hay tim giao diem cua 2 do thi do
cho ham so y=f(x)=2x va y=g(x)=18/x . khong ve do thi ham so hay tim giao diem cua 2 do thi do
