Answer:
D
Step-by-step explanation:
Both lines begin or end at x = - 1
The top line has a y- intercept of 4 and an open circle at x = - 1 indicating it cannot equal -1, thus
2x + 4 for x > 1
The lower line has a closed circle at x = - 1 indicating it can equal -1, that is
x + 2 for x ≤ - 1
x + 2 if x ≤ 1
2x + 4 if x > 1 → D
