Bump!So R- means <0?

What's the difference between open and closed brackets?
How about when stating the domain and range. How do you find out if it's open or closed?

Depends on whether the domain includes the endpoint or not.bump!
How do you know weather to state the domain with open or close brackets?
Some questions ask you to state the domain and range of a graph. How do you know weather to state it as open or closed?Depends on whether the domain includes the endpoint or not.
If they give you the graph, you can look at it to see if an endpoint is included or not.Some questions ask you to state the domain and range of a graph. How do you know weather to state it as open or closed?
So if it was a parabola that had arrows going in each direction would it be infinity and open bracket?If they give you the graph, you can look at it to see if an endpoint is included or not.

Is this for the domain or the range?

so the range would be (lowest y value, infinity)?Domain
Anyone?What is the domain and range of y = 3/(x+2)^2 + 2?
is there any other domain possible?Assuming the natural domain; i.e. largest set of values of x that is allowed. For this question, where presumably we are dealing with a real function, it is all real values except x = -2; when x = -2, you will have a division by zero - which is a Cardinal sin in maths. The corresponding range is all y > 2; i.e. all real numbers greater than 2.
Yes. What Drongoski gave is the natural domain (assuming we are dealing with functions of a real variable). You can read up about this here: https://en.wikipedia.org/wiki/Domain_of_a_function#Natural_domain .is there any other domain possible?
any thoughts?How should I prepare for my maths application task, which is in a week.?
