For a point x = ($x_1$, $x_2$, ... ,$x_n$) in $mathbbR^n$, define $T_x$ to be the step function on the interval [1, n + 1) that takes the value $x_k$ on the interval [k, k + 1), for 1 $leq$ k $leq$ n. For p $geq$ 1, define $| x|_p$ = $| T_x|_p$, the norm of the function $T_x$ in $L^p$[1, n + 1). Show that this defines a norm on $mathbbR^n$. State and prove the Holder and Minkowski Inequalities for this norm.
I know this question has been posted before, however, no straightforward answers were provided. I know that in order to show something is a norm, we need to show the four conditions. However, I don't know how to do that in relation to this problem. Any concrete steps/answers are appreciated.

Honestly, the step function confuses me. It's difficult to see what the norm is when a step function is involved.

This is pretty simple. The norm is just the usual $p$-norm for vectors: $|x|_p = left(sum_k=1^n|x_k|^pright)^1/p$.
