Can someone please help me with this of identifying the domain and range

I'll try my best, but I am a little rusty!

Domain (D) is all possible x values

Range (R)  is all possible y values

I don't know how your teacher taught you how to write the values, but here is how I do it

7. D: { all real numbers}, R: {-3 ≤ y ≤ 2}

8. D { -1 ≤ y } or { -1 ≤ y ≤ ∞ }, R: all real numbers

9. D: {2}. R: all real numbers

10: D: all real numbers, R: {-4}

11. D: {-2 ≤ x < 5}, R:  {-2 ≤ y ≤ 1}

12: D: {-4 ≤ x ≤ 5}, R: {-3 ≤ y ≤ 5}

13 D: { -∞ ≤ y < 2 }, R: {-∞ ≤ y < 0}

14: D: {-2 ≤ x ≤ ∞}, R: {-4 ≤ y ≤ ∞}

Hope I helped! Message me if you have any questions or concerns! :)
