Cho ham so y=f(x)=2x

a)Tinh f(-2);f(2)

b)Ve do thi ham so y=2x

c)Cac diem sau diem nao nam tren do thi cua ham so A(2;4), B(-3;6), C(-1 phan 2;1)

cho ham so y=f<x>=3x{1}

A,ve do thi ham so {1}

B,tinh f(0);f(-1/3)

Cho ham so y=f(x)=-2

Tính f(-2);f(4)

Ve do thi ham so y=-2x

Cac diem sau diem nao nam tren do thi ham so da cho:A(2;4),B(-3;6),C(-1/2;1)

cho ham so y=f(x)=(m-1) ( m khac 1 )

a, xac dinh gia tri cua m de do thi ham so di qua diem A(1;-3).ve do thi ham so vua tim duoc

b,voi ham so tim duoc o cau a,tinh f(2/3), f(-4)

c,diem M(-1;3) va N(6;-9) co thuoc do thi ham so tim duoc o cau a khong?

cho ham so y=\(\dfrac{3}{2}\)x =f(x)

a)tinh f(-1);f(2);f(-4)

b)ve do thi ham so tren

cho ham so y=2x

a. tinh f(2);f(-2)

b. ve do thi cua ham so tren

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

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 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
