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
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
ve do thi cua ham so y - x =10
ve do thi cua ham so y=1/2|x|
Cho 2 dai luong y va x ti le thuan voi nhau, biet rang khi x=4 thi y=2
Bieu dien y theo x
Coi y ham so cua x. Ve do thi ham so tim dc
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
ve do thi ham so y=\(\frac{-1}{4}\)x voi x\(\in\eta\)
diem (-2;1/2 ) co thuoc do thi ham so khong
