Solve the below:
Q: Consider the linear system x' = Ax, where A is a n x n real matrix. If x = x(t) is a solution of the linear system, we define:
G(x) = {x(t) : t E R),
which is the set of points on the solution curves x=x(t) in R^n. The set G(t) is called the graph of x = x(t) .
Show that if x(1) = x(1)(t) and x(2) = x(2)(t) are any two solutions of the linear system, then either the intersection of G(x1) and G(x2) is empty, or G(x1) = G(x2), that is their graphs are either disjointed or the same.
