Short Answer

Expert verified

For all ε>0, there exists δ>0such that if 0<|x-c|<δ. Then,

role="math" localid="1648190933202" kf(x)-L<ε

whererole="math" localid="1648190955831" L=klimx→cf(x).

Step by step solution

01

Step 1. Given information.

The constant multiple rule for limit is

lim(kx→cf(x))=klimx→cf(x), for any real number k.

02

Step 2. Statement.

For all ε>0, there exists δ>0such that if 0<|x-c|<δ.

Then,

kf(x)-L<ε

whereL=klimx→cf(x)
