Help with all parts please.

Let \( A \in \mathbb{R}^{m \times n} \) and \( b \in \mathbb{R}^m \). Express the following problems as Linear Programs (LPs): (a) \(\min_{x \in \mathbb{R}^n} \|Ax - b\|_{\infty}\) (b) \(\min_{x \in \mathbb{R}^n} \|Ax - b\|_1\) (c) \(\min_{x \in \mathbb{R}^n} \|Ax - b\|_1 + \|x\|_{\infty}\) *Hint*: use (a variant of) the epigraph form.
