Thread: [SOLVED] fog is a linear transformation, is f and g?

Hello,

I'm struggling trying to see if f and g are linear transformation when fog is a linear transformation.

fog a linear transformation =>? f and g are linear transformations

Let's say g
(x,y) |-> (x+2,y)

and f
(x,y) |-> (x-2,y)

fog will be a linear transformation but not f and g... right?
I'm not sure to have the correct definition of what is linear.

Thanks (:

An application is said to be linear if

Allright, so it's correct.
