Ineed answers for all of these and you.

I can't do the domain and range but here are the function answers:

1)N

2)N

3)Y

4)N

5)Y

6)Y

7)N

8)N

9)Y

I hope that helped. Sorry I couldn't do the other parts.

b) well because you get well

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
