Using continuity concepts, it is found that the correct options are:
- The function is continuous at x = -4.
- The function has an infinite discontinuity at x = -1.
-----------------------------
A function f(x) is continuous at x = a if:

-----------------------------
- At x = -4, there are no changes in the definition of the function, thus, it is continuous.
- At x = -1, we have that:


- A different definition depending on the which side of -1 the function is, thus, it is a jump discontinuity.
