Any answers to these of domain and range and the bottom too.

Step-by-step explanation:

7. Domain = All real numbers; range = all real numbers

8.  Domain All real numbers.  range all real values of y ≥ -2

9.   Domain  -2  ≤  x  ≤  2;   Range  -3  ≤  y  ≤  3

10.  Domain All real numbers;  range  -1  ≤  y  ≤  1

As for the other questions All are functions except   13, 14 , 15, 17 and 19.

we see that 13, 14 and 15  are one-to many relations and so are 17 and 19 - in these last 2 cases we also see that their graphs fail the vertical line test. ( You can  draw a vertical line which passes through 2 points on the graph.).

Hi!

Step-by-step explanation:

2/3 is the slope and which is our final answer.

Hope this helps you!

Have a nice day! :)
