limits
● If the limit = 0 then its a factor
● When the function has a di erent value to the other equal side,
then the limit dosnt exist.
● When you get error,the limit dosnt exist
● Also if you can't factorise, then the limit doesn't exist
Eg; x2 - 4
------- = undefined when x = 2
4x - 8
Eg; x2 - 2
------- = 4 x = 18
4x - 8
1. Now consider this function again…
x2 - 4
F(x) = -------
4x - 8
Determine the value if ….
Lim x2 - 4
X⇾2 F(x) = -------
4x - 8
(t i me , ma x = 2)
