Initially, let $\displaystyle x^{(0)}$ be the linear combination $\displaystyle a_1x_1 + a_2x_2 + ... + a_nx_n$, of A's linearly independent eigenvectors, with each constant $\displaystyle a_i \neq 0$. Find two expressions for the population distribution $\displaystyle x^{(1)}$ after one generation; one using products involving matrix $\displaystyle A$, the other in terms of $\displaystyle A$'s eigenvalues."

Now, the question is a little blurry, and so I've come to an answer of which i'm not sure if is correct...

My Answer:

Expression #1 => $\displaystyle x^{(1)}$ = $\displaystyle Ax^{(0)}$

Expression #2 => $\displaystyle x^{(1)}$ = $\displaystyle \lambda x^{(0)}$

Please indicate for me if I'm wrong...and if so could you please direct me on how i should go about this question.

Many thanks :)
