Answer:
The 3th answer is correct.
for x<2, form graph we know that if x=0 than y=-3.
For x<2 in 3th we have y=1/2x-3, so for x=0, y=(1/2)*0-3=0-3=-3. It fits.
For x=2, from graph we have that y=-2.
For x>=2 in 3th we have y=3x-8, so for x=2, y=3*2-8=-2. It fits.
These answer fit also i for first, but breakpoint for y from graph is point 2 not point -2, so the answer is 3th.
