An application is said to be linear if
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 (:
