Answer 1

check the picture below.

notice, the piece-wise function has 3 subfunctions, so we graph each one, and constrain their domain to the provided values, notice the dashed lines are the continuation of that line but is not part of the piece-wise because is outside the domain.

the solid dot at the endpoint means, that endpoint number is included for that line, whilst the hollow dots on the endpoints mean, is not included in the graph.
