Answer 3

I hope so. I'd have to see your problem before I can honestly answer that question.

Answer 4

problems 2 - 4

Answer 5

Those are a little hard to read, but here's the general procedure:
Divide up the X axis into the separate domains. e.g. for #2, the three zones are x<1, from -1 to 1 and x>1. Take the first function, y=-x and graph it like you would normally, but only include the part that lives in the x<1 zone on your graph.

Answer 6

Does that make sense?

Answer 7

a little
do u want me to type out the problems?

Answer 8

No, but here. I'll draw up a graph and you can 'reply using drawing' to show me what you think they should look like.
