@Jeb: No, I have solved this. It is $\phi$ dependent.

Thank you! I was onto that type of comparison, but I was not sure if that completed the proof.

Thanks Paul. But how do you think when you set up the span{${x, x^2, x^3}$}? Because to me I cannot find a good way to think when I am supposed to find a base in this case.

However, it seems pretty obvious that it is so when I look at @AnonSubmitter85's answer below.

@JoseAntonio: I don't think we have been going through what a 'map' or an 'isomorphism' are, it sounds unfamiliar to me.
