Chapter 2 - Section 2.5 - Continuity - 2.5 Exercises - Page 124: 18


Discontinuous because the limit as x approaches -2 does not exist.

Work Step by Step

For f(x), as x approaches -2, the left-sided limit equals negative infinity and the right-sided limit equals positive infinity. Since the left-sided and right-sided limit do not equal, the limit does not exist and therefore the function is discontinuous at x=-2.
