## Homework Statement

Check if the linear transformation [tex]f : \mathbb{R}^2 \rightarrow \mathbb{R}^2[/tex], defined with [tex]f(x,y)=(x+y,y)[/tex] is isomorphism? If so, find the linear transformation [tex]f^-^1[/tex]

## Homework Equations

V and U are vector sets. The linear copying [tex]F:V \rightarrow U[/tex] which is bijection is isomorphism.
