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.
