Okay and... what are you confused about
Domain are all the x - values included in the graph.
In this case all the x - values are (listed from smallest to largest and excluding duplicates):
{-3, -2, 0, 1}
^^^This is also your domain
NOTE: There are several different ways to write domain. Let me know if this is the way you need it to be written in
Hope this helped!

Answer:8n-4
Step-by-step explanation:
8-3x=5*2
8-3x=10
-3x=10-8
-3x=2
x=-2/3
Answer:
Step-by-step explanation:
Work done= rate *time
let time taken by X to produce w widgets be t days
rate = w/t
Since X take 2 days longer rate for Y would be
rate= w/t-2
combined rate is (w/t+w/t-2)
Since in 3 days both x and y can produce 5w/4
(w/t+w/t-2)= 5w/4
5t2 -34t +24=0
(t-6)(t-4/5)=0
t=6 or t=4/5(not possible because t-2(time taken by Y) comes out to be -6/5 which is not possible)
so t=6 days which is the time taken by X to produce w widgets
so time taken to produce 2w widgets will be 12 days.
