@DanJS

Answer 16

ya

Answer 17

the domain is all the possible values for X in that graph

Answer 18

hey dan sorry if im annoying you with my math problems but i came across another one but this time it had a graph so im kinda trying to firgure out if someone can explain for me

Answer 19

The arrow on the right side of the graph means that it continues on to +infinity

Answer 20

the solid dot at -3 means that it can = -3

Answer 21

so im not suppose to find the x values on the line or just anywhere?

Answer 22

the domain is all the values for X
which is any number bigger than or equal to -3

Answer 23

no it just wants to know what are all the possible values that X can be

Answer 24

why did i think that would be harder then it is thank you and sorry

Answer 25

for example above, the graph has a solid dot at (1,2) and a open dot at (-2,-3)

the domain is all possible X values, here it is greater than -2 but less than or equal to 1
the range is all possible Y values, here it is greater than -3 but less than or equal to 2
