Answer 1

Answer:

a = -4, 5

Step-by-step explanation:

You're looking to find points whose limits are equal to -4, which means that they must fufill two requirements:

1. The values immediately outside the point are pretty much -4
2. The two sides must both be close to -4.

Additionally, if a point is simply equal to -4, the limit will also be equal to -4.
