What is Limit of StartFraction x minus 1 Over x squared minus 1 EndFraction as x approaches negative 1? –2 –1 0 DNE ANSWER: D

Step-by-step explanation:

 Limit    of    (x - 1))/(x^2 - 1)

x---> -1

As x  approaches -1 from negative side ( x < -1) the  limit is -infinity.

As x  approaches -1 from positive  side ( x > -1) the  limit is +infinity
