The dot is closed at x = 3 and it appears to go on without end along the x axis...so$$x \ge 3$$

anonymous · Answer

Omygosh, that's what I got too! :D

Remember your domain is your x values.  Your graph starts at x = 3.  y = 1, but y is the range, so it doesn't matter in this question.  TY for the medal!

Good job, lilia222!

goformit100 · Answer

x >= 3

it is so because see the graph you have to just find all the possible x values when domain is asked in the question

goformit100 · Answer

in the graph you can see .....-2, -1, 0, 1, 2 ....... values dont show x values for graph

goformit100 · Answer

but see that 3 is included in given graph

goformit100 · Answer

so 3 is also a domain of the given graph.... and carry on further...... 4, 5, 6.... onwards give a particular x value here so, 

domain is x >=3
