(a) State precisely the definition of: a function f is continuous at a point
a ∈ R.
(b) At which points x ∈R is the function:
f(x) = sin(1/x)continuous?
You may assume that g(x) = 1=x is continuous on its domain, and
h(x) = sin(x) is continuous on its domain.
(c) Let f and g be functions such that:
1. g is continuous at 0, and g(0) = 0.
2. For all x∈ R, lf(x)l <= lg(x)l.
Use the
ϵ− δ definition of limit to show that f is continuous at 0.
I did part (a) and (b) but i don understand how to do part(c).Can any1 provide guidance on it?thanks
