Answer:
see picture and explanation
Step-by-step explanation:
on the graph if theres closed dots you use brackets [ ] for domain and range
closed dots mean the line stops on those exact numbers
if there's open dots or arrows you use parenthesis ( ) for domain and range
open dots or arrows means that the line continues forever (infinity)
Domain is the x values
on the first one the dots on each end are at -4 and 4 on the x axis
on the second one, since its arrows it continues forever so its negative infinity to infinity
(always remember for domain and range to put the smaller number first)
Range is the y values
the first one the dots stop at -1 and 5 at the ends on the x axis
on the 2nd question there are arrows so it never stops so its negative infinity to infinity again
End value is just what the graph is doing. so for both questions the graph starts at the lowest left corner which means its negative infinity going to negative infinity on that side from the origin (middle of graph) and then it rises from infinity to infinity on the other side of the origin. started positive and continuing to go positive.
I might have explained the end behavior incorrectly since its been awhile since I've done this. look up "end behavior" and look at images to get a better understanding
