LetF:RRbe a function. We say thatfhas:
 PROPERTY 1 iflimh0fh-f0hexists and is finite, and
PROPERTY 2 iflimh0fh-f0h2exists and is finite.
Then which of the following options is/are correct?

Options:(select one or more)

Answer:
B, D
Solution:

A fx=x
limh0h-0h=limh0h=0
B fx=x23
limh0h23-0h=limh0h16=0
C fx=xx
limh0hh-0h2=limh0hh=1, if h0+-1, if h0-
Does not exist
D fx=sinx
limh0sinh-0h2=limh01hsinhhdoes not exist
