"Using Definition 6.3.6 Prove the following statement
Let f and g be real-valued functions defined on (a, ). Suppose that lim f(x) = L and
lim g(x) = M where L, M E R.
Then lim (fg)(x) = LM.
6.3.6 DEFINITION Let f: (a, 0) → R. We say that Le R is the limit of f as x→ o, and we
write
lim f(x) = L,
provided that for each &>0 there exists a real number N> a such that x > N
implies that | f(x) – L| < ɛ.
