What do you think it is?

have you tried to translate the phrases given as a mathematical proposition?

[terse willow]

The matrix associated with the composition of two linear transformations is the product of the matrices associated with each linear transformation??

[terse willow]

C!

[cedar linden]

and how do you come to this conclusion?

[cedar linden]

yeah for example

[terse willow]

Applying a linear transformation
A to a vector u
Umm that means matrix multiplication: A(u)
Applying another linear transformation B after A
means: B(Au )=(B⋅A) u
The composition of the two linear transformations corresponds to the product of the matrices

And I got this for the box

[cedar linden]

yeah that's correct, so C is correct

is it multiple choice tho? because maybe im wrong bc im french and we dont use the same terms, but A looks correct to me too

[terse willow]

No there’s 1 correct answer ☹️

[cedar linden]

C is definitely correct

like you said

[terse willow]

Okay thank you then! I appreciate it a lot

C better describes that particular scenario, though the statement in A isn't wrong by itself.
