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=(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 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 = f(x) = ax + 4 co do thi ham so di qua A(a+1; a^2-a). Tim A
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
diem n (3,5;14) thuoc do thi ham so y=ax do thi ham so kia di qua diem m (m;10) vay m=
do thi cua ham so y=ax(a khac 0) luon di qua diem nao
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 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
