Answer to Problem 12CT
(a) function is not continuous at
(b)given function is continuous at
(d)at
Explanation of Solution
Given information:
(a) at
At first we find the right limit :
Here ,
Left limit
[as same from left limit]
Hence,
And function value at
Hence, given function is continuous at
(b)
So,
And
Hence,
Hence, function is not continuous at
(c)
Since,
Limit do’t exist
So, the function is not continuous at
(d)
