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
