Answer:
d
Step-by-step explanation:
Both lines begin or end at x = 2.
The line on the left has a y- intercept of 2 and an open circle at x = 2 indicating that it cannot equal 2, that is
x + 2 for x < 2
The line on the right has a closed circle at 2 indicating it can equal 2, that is
x + 1 for x ≥ 2
Hence
y = x + 2 for x < 2
y = x + 1 for x ≥ 2 → d
