Definition: Let $X$ be a Banach space. We say that a bounded linear functional $x^*:X\to \mathbb{R}$ is an **extreme point of** $B_X = \{x\in X:\|x\|_X\le 1\}$ if whenever $$x^* = \frac{1}{2}(y_1^*+y_2^*)$$ for some $y_1^*,y_2^*$ with $\|y_i^*\|_{X^*} \leq 1$ for all $i=1,2,$ we have $x^* = y_1^*=y_2^*.$ ____ > **Question**: Given a Banach space $X.$ Is it true that there exists an bounded linear extreme functional $x^*:X\to\mathbb{R}$ such that $$x^*(x) = 1$$ for some $x\in X$ with $\|x\|\leq 1?$ In other words, is it true that every Banach space has at least one extreme functional that is normed by some point?
