Find the point(s) of discontinuity for the function f(x) = x2 + 1+ |2x − 1|.



![]()
![]()
![]()
There are no points of discontinuity as the function is continuous.

Consider the function:
![]()
If f (2) = 3, determine the values of a and b for which f (x) is continuous.
There is only a question of continuity at x = 1.



For the function to be continuous:

On the other hand there is:

Solve the system of equations and obtain:
a = 1 b = −1
3
Given the function:

Determine the value of a for which the function is continuous at x = 3.



4
Given the function:

Determine the points of discontinuity for the function.
The exponential function is positive for all x
, therefore the denominator of the function cannot be annulled.
There is only doubt of the continuity at x = 0.


Solve the indeterminate form dividing by 

The function is continuous on
− {0}.

Calculate the value of k for the following continuous function.



Therefore there is no limit for the function and there is no value that would make f(x) continuous at x = 0, regardless of what value k is given.
