I'm not sure if these are correct or not. (I don't think so). Also, 4 and 5 need to be in set notation and 7 and 8 need interval notation. Please check my work. Sorry.
Domain = x values covered by the graph
Range = y values covered by the graph
4 looks good
5 Domain is correct
Range is (-inf, 0 )
7. Domain [ -3, 5 ] ⇒ -3 ≤ x ≤ 5
Range [-4, 4] ⇒ -4 ≤ x ≤ 4
8. Domain (-inf, inf ) ⇒ -inf < x < inf
Range [-3, 3 ] ⇒ -3 ≤ x ≤ 3
Great!! Thank you for the help!
