Nguyễn Quang Thành zậy là sao?
f(2) = 2.2 + 2 = 4 + 2 = 6
f(-4) = 2.(-4) + 2 = -8 + 2 = -6
f(0) = 2.0 + 2 = 0 + 2 = 2
f(2)=2.2+2=4+2=6
f(-4)=2.(-4)+2=-8+2=-6
f(0)=2.0+2=0+2=2
f(2) = 2.2 + 2 = 4 + 2 = 6
f(-4) = 2.(-4) + 2 = (-8) + 2 = -6
f(0) = 2.0 + 2 = 0 + 2 = 2
f(2)= 2.2+2=6
f(-4)= 2.(-4)+2= -6
f(0)= 2.0+2= 2
tick cho mik nhé
