comment Proving a function is a linear transformation
@ArturoMagidin: Thank you - that is exactly the hint/tip I was looking for. I've only just noticed that I can edit my original question, which I will do so now.

comment Proving a function is a linear transformation
It isn't actually homework - it's related to one of the exercises in my textbook. I think I'm having a conceptual problem of how the (2x+1) applies to the original p(x) (or the p(x)+q(x)), which is why I'm asking for an example.

comment Proving a function is a linear transformation
Please help me out a little, I'm really trying to get my head around this conceptually. Can you explain by 'verify the (p+q), evaluated at 2x+1' means, or how I go about it. Thanks in advance for your patience

comment Proving a function is a linear transformation
Could I ask 2 more points of you, what would be the result if P(x)=1 (instead of p(x)=x^2 in your example. And could you explain the processing of showing how L(p+q)=L(p)+L(q) in this instance. Thanks

I understand now the differenes you have shown me. Could I ask 2 more points of you.

comment Is any relation that is reflexive also symmetric and also transitive?
Thank you. I understand now, I think my mind got too focused in on the specific instances (only pairs of the form (x,x).
