Question

Is this a function or the result of a function?

Answer 1

The function in question.

Answer 2

I'm thinking result, but I got no explanation.

Answer 3

I think it depends on context, but I'm inclined to agree with IsTim because the answers are ordered 2,3,1, which makes me think they come from somewhere else...

Answer 4

The question did ask "derive the matrix associated with this transformation." So I'm going to agree with you both :)

Answer 5

well hold on now
'this transformation'
that is a mapping (a one-to-one mapping) so that would bin fact be a function!

Answer 6

I'm wrong!

Answer 7

given the information so was I...
but now I'm pretty sure it's a function

Answer 8

Is this the answer you got from the above problem, or...?

Answer 9

Okay, let me post the question to clarify: "Using the definition of linearity, verify that the following permute function, f, is a linear transformation"

But then it asks me to derive a matrix. So lets say I do derive a matrix, I multiple the vector [x1, x2, x3] with the matrix, shouldn't I get [x2, x3, x1], which is the image I posted earlier?

Answer 10

i dunno

Answer 11

the matrix that you derived, you got through using your permute function?

Answer 12

The above image was given by the question. It looks like a vector, which is why I'm confused. I don't if it is F(x) equaling to a resulting vector or if that image indeed is the matrix it is asking me to derive.

Answer 13

hm... Now I'm completely unsure as well!
sorry, I think you may have to try your luck with this question again :/
