Final answer:
To show that the transformation t is not linear, we need to find a counterexample to one of the properties of linearity: additivity or homogeneity.
Step-by-step explanation:
To show that the transformation t is not linear, we need to find a counterexample to one of the properties of linearity: additivity or homogeneity.
Additivity: We need to show that t(u + v) is not equal to t(u) + t(v) for some vectors u and v.
Homogeneity: We need to show that t(ku) is not equal to k * t(u) for some scalar k and vector u.
