The function values for f (x) near x = 1 are given in the table below.

x
0.9
0.99
0.999
1
1.001
1.01
1.1
f (x)
4.40
4.25
4.02
5.00
3.98
3.75
3.60

Use the table of values to evaluate
1
5
4
does not exist
IMO the limit does not exist.


Also, this

. Suppose f (x) is a function such that . Which of the following can be true?
I. f (5) = 0
II. f (5) = 2
III. f (5) is undefined
II only
I and II only
I only
I, II, and III


Again, IMO I, II, and III are correct.

Pleeease help!
