Question

Please help me out with this :)

Answer 1

D

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
