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=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
cho ham so : y=f(x)=1/2x
a,tinh f(-1),f(3),f(6)
b,ve do thi ham so da cho
Cho ham so y=f(x)=-2x
a, Ve do thi ham so tren mat phang toa do Oxy
b,Tim a biet f(a-4)=6
cho ham so y=f(x)=ax.biet f(-3)=2
a, tinh he so a va ve do thi ham so
b, tim x de f(x)=-6,ungvoi gia tri a tim duoc o cau a
ve do thi ham so sau cung 1 he truc oxy y=3x , y=-2x tinh dien tich tam giac tao boi 2 do thi ham so tren va duong thang y = 3/2
cho ham so y=(2m^2+m-3)*x. a)ve do thi cua ham so m=2.b) tim m biet do thi ham so di qua A
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
