The key here is for the function to be continuous, all the y-values have to be equal when each of the pieces comes together.

#### Explanation:

So, let's take the first two functions,

When the two pieces meet at x=a, in order for them to be continuous, the y value must be equal on both sides.

So, one way to solve these is to make the two functions equal each other, so

Therefore, x = -1

This matches option B.
