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 (:
