As explained in Example 1.2.3 (right below the definition of limit), why does the function not have a limit as 9 x 1 By the way, when the function doesn't have a limit, we can say the limit Does Not Exist and we can write it this way: lim g(x) DNE x 1 Because you only need to let x approach 1 from one side Because there is a hole in the graph When x approaches 1 from the left, g approaches a different value than when x approaches 1 from the right. So since g does NOT approach a single value as x approaches 1 from both sides, the limit doesn't exist. Because the graph of g is made up of different functions

Question
As explained in Example 1.2.3 (right below the
definition of limit), why does the function
not have a limit as
X
9
1
By the way, when the function doesn't have a
limit, we can say the limit Does Not Exist and
we can write it this way:
lim g(x) DNE
x-1
Because you only need to let x approach 1 from
one side
Because there is a hole in the graph
When x approaches 1 from the left, g approaches
a different value than when x approaches 1 from
the right. So since g does NOT approach a single
value as x approaches 1 from both sides, the limit
doesn't exist.
Because the graph of g is made up of different
functions
