It’s linear in terms of its order but it’s not a linear transformation, which must satisfy: f(c*(a+b)) = c*f(a) + c*f(b) Where c is a scalar. A and b are

It’s linear in terms of its order but it’s not a linear transformation, which must satisfy: f(c*(a+b)) = c*f(a) + c*f(b) Where c is a scalar. A and b are abstract objects. Examples include vectors, real numbers, and functions themselves.
