I didn't get affine and differece between affine and linear?

piecewise linear does not guarantee convex / affine. Actually it is affine when you have a piecewise affine function composed by the max of a bunch of affine function. However, you may see lots of other linear spline functions like ReLU network that are not convex/affine. And you need mixed integer linear programming to solve that kind of tasks (introduce integer variables to denote which piece of function you are at).

Didn’t really understand the quasi convex sub level set arguments from before

You find a feasible point of a convex function phi(x) s.t. f(x)
