Let D* = [0,1]x[0,1] and define T on D* by T(u,v)=(-u^2+4u, v). Find the image D. Is T one-to one
Homework Equations
The Attempt at a Solution
I have no idea... I don't know how to do it.
The solution is [0,3] x [0,1]... yes it is one to one.
am I supposed to say det A does not equal zero or use the u=u' v=v' approach?
and... how do I find D? i don't know how to go about this.
Could someone give me a similar example and solve that?
