induced norm of a one to one function












0












$begingroup$


Let $V subset C^0(mathbb{R}, mathbb{R})$ be a vector space and $ f: V to mathbb{R}^n : g mapsto (g(i))_{i=1,dotsc,n}$ a one to one function.



Then in my lesson, they are talking about the norm of $V$ induced by the function $f$.



I don't understand what it is. I know that on $mathbb{R}^n$ there is the euclidian norm, but then why $f$ defined a norm on $V$ and what is this norm ?



Thank you!

    If $f$ is nonlinear, there doesn't seem to be any natural way to approach this...
