Algebra-2

For the function :

1. As  approaches , the denominator  becomes extremely large in magnitude. Since the numerator is a constant (-1), the value of the function approaches 0.

2. As  approaches 0 from the left,  is a small negative number. The denominator  is a negative number with a small magnitude. Thus, the function value approaches .

3. As  approaches 0 from the right,  is a small positive number. The denominator
