Question

I'm pretty sure that the answer is Domain:(-infinity,3] Range [3, -infinity). Am I right?

Answer 1

for domain you should read the graph left to right
for range you should read the graph from down to up

Answer 2

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

Answer 3

(a,b)
you should always have that a<b not a>b

Answer 4

Ok, so range is (-infinity, 3]?

Answer 5

that i can agree with for the range

Answer 6

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)?

Answer 7

or f(5)
or f(6) and so on...

Answer 8

or f(pi)

Answer 9

I don't know

Answer 10

The graph seems to be expanding and seems like it will eventually reach the 5 and 6 on the x-axis

Answer 11

right but your domain doesn't include those numbers
your domain for some reason stops at x=3
