Q: Local properties of Baire 1 functions

Sam SandersA Baire 1 function $f:[0,1]\rightarrow \mathbb{R}$ need not be bounded. However, thanks to the Baire category theorem, we know there is $N\in \mathbb{N}$ and a sub-interval $(c, d) \subset [0,1]$ such that $(\forall x\in (c, d))( |f(x)|\leq N)$. In other words, a Baire 1 function may not be bou...
