الجبر طلب تعريف support ofpoint

[terooz]

السلام عليكم
ممكن حد ي يعرف support ofpoint​

 

[ابن الخطاب]

simply, let f be a function and A belongs to [0,1], we call f is convex at apoint x in Dom (f) if

f(x)<= A f+ (1-A) f(z) whenever x= Ay+(1-a) z, which is equivalent to say that f has a support at x
