EXPosition Style

As a pedagogical device for describing functions such as the one

below

a

where two formulae, f1 and f2, are necessary for adjoining domains but

the function is continous at the boundary point, I usually write the

description in the form

f(x) = f1(x) for x =< a

f(x) = f2(x) for x >= a

The astute reader will note that the domains overlap, but that

f1(a) = f2(a), so no semantic ambiguity oBTains.
