for domain you should read the graph left to right for range you should read the graph from down to up
both of your answers are wrong and for different reasons domain you did not go far enough to the right range you for some reason listed the higher numbers first then the lower ones
(a,b) you should always have that ab
Ok, so range is (-infinity, 3]?
that i can agree with for the range
now the domain you read the graph from left to right (think x-axis since that is where we are gonna grab our numbers from) why do you think the graph doesn't exist at f(4)?
or f(5) or f(6) and so on...
I don't know
The graph seems to be expanding and seems like it will eventually reach the 5 and 6 on the x-axis
|dw:1440650387324:dw| right but your domain doesn't include those numbers your domain for some reason stops at x=3
So does that mean that the domain is 3?
no that would mean the graph would only exist at x=3
your graph looks like exist for all x
I was saying your answer says the domain stops at x=3
Oh ok, so it would be (-infinity, infinity)?
Ok, thank you!
