(1 point) Let f:R→R3 be defined by f(x)=⟨6x,−6x,−9x⟩. Is f a linear transformation? f(x+y)= 6(x+y),-6(x+y),-9(x+y) . f(x)+f(y)= (6x,-6x,-9x) + (6y,-6y,-9y) . Does f(x+y)=f(x)+f(y) for all x, y∈R? f(cx)= (6(cx),-6(cx),-9(cx)) . c(f(x))= c ( 6cx,-6cx,-9cx ). Does f(cx)=c(f(x)) for all c, x∈R? Is f a linear transformation?
