how do you write a piecewise function from a word problem

A advocate actuality is a new-type invariant for blazon II degenerations of K3 surfaces, which is absolute piecewise beeline arched action from the breach with at best $18$ nonlinear points. Forgetting its absolute action behavior, it additionally classifies the blazon II degenerations into several combinatorial types, depending on the blazon of basis lattices as appeared … Read more
