## Homework Statement

Let's say that [tex]f: \mathbb {R}^3 \rightarrow \mathbb {R}^2[/tex], [tex]g: \mathbb {R}^3 \rightarrow \mathbb {R}^2[/tex], and [tex]h: \mathbb {R}^2 \rightarrow \mathbb {R}^2[/tex] are linear copying defined with [tex]f(x,y,z)=(y,x+z)[/tex], [tex]g(x,y,z)=(2z,x-y)[/tex] and [tex]h(x,y)=(y,2x)[/tex]. Find the linear copying:

h o f and h o g

## The Attempt at a Solution

Sorry, but again, I don't know the principle of solving this task. My book is not good at all. Thanks from the start.
