Prove statement 6 of theorem A. |f(x) g(x) - 1.M = |f(x) g(x) - Lg(x) + Lg(x)

Question:

Prove statement 6 of theorem A.
|f(x) g(x) - 1.M = |f(x) g(x) - Lg(x) + Lg(x) - LM|
= |g(X) [f(x) - L] + L[g(x) - M]|
‰¤ |g(x) ||f(x) - L| + |L|| g(X) - M|
Now show that if
Prove statement 6 of theorem A.
|f(x) g(x) - 1.M =

Then there is a number δ1 such that
0
