[連續] 一些問題
是非題 :
a. If the function h(x)=f(x)+g(x) is continuous at the point c
,then f(x) and g(x) are also continuous at c.
b. If the function f(x) and g(x) are differentiable at the point c then
the function h(x)=f(x)+g(x) is differentiable at c.
c. Let f(x) and g(x) are functions on R ,then lim f(x)+lim g(x)=lim(f+g)(x)
x->c x->c x->c
d. If f(x) is a function on the closed internal [a,b] with f(a)<f(b),then
for all L:f(a)<L<f(b)there exists c: a<=c <=b such that f(c)=L
我不知道對還是錯 還有解釋= = 3Q~
