Graphing Radical Functions (just find domain and range.) Hi! I am working on the study of graphing radical functions. I have already graphed these functions, I just do not understand how to write domain&range for both. I have to write it in terms of "all real numbers" I will include all 5 graphs below. Would really appreciate help.

Best ResponseYou've already chosen the best response.0okay well basically you have to find the asymptote of each function and state that that's the only point that the function does not equal (e.g. all real numbers except"whatever xintercept the asymptote is at")

Best ResponseYou've already chosen the best response.0do you know how to find the vertical asymptotes ?

Best ResponseYou've already chosen the best response.0I am not sure how to do that. I was sadly not introduced throughly to the unit :(

Best ResponseYou've already chosen the best response.0Yeah I am not totally understanding how to relate that to finding domain and range i'm a bit confused

Best ResponseYou've already chosen the best response.2For the first one, \(f(x) = \dfrac{1}{x+1}\) take denominator =0, solve for x, what do you get?

Best ResponseYou've already chosen the best response.2knock knock!!! x +1 =0, x =??

Best ResponseYou've already chosen the best response.2yes, domain relate to x, right? but you can't take x =1 since it makes the function undefined, right? Hence D = \(\mathbb R/{1}\)

Best ResponseYou've already chosen the best response.0So that would make the domain for the first graph undefined then?

Best ResponseYou've already chosen the best response.2How about the range? Look at the graph, y goes from infinitive to +infinitive but at 0, Hence Range is \(\mathbb R/0\)

Best ResponseYou've already chosen the best response.2A little bit difference. domain is all numbers of x that make the function defined. 1 makes the function undefined, hence domain is all real number BUT 1

Best ResponseYou've already chosen the best response.0ahhhhhhhhhhhhh. That makes sense. I understand. I never understood the "all real numbers except.. ext."

Best ResponseYou've already chosen the best response.0i'm sorry, I do not understand the notation by "R/0" you mean that the range is all real numbers but 0?

Best ResponseYou've already chosen the best response.2it is not R/0. It is \(\mathbb R/\{0\}\). That the correct notation.

Best ResponseYou've already chosen the best response.2what is the second function? \(f(x) = \dfrac{1}{x2}+1\)??

Best ResponseYou've already chosen the best response.0x would equal 2 here. would this mean that the domain is all real numbers except for 2?

Best ResponseYou've already chosen the best response.0and how would I find the range? i did not totally understand how you did that for the first graph

Best ResponseYou've already chosen the best response.2to find the range of a radical function, you need asymptotes, that are the line the graph is never touch. like the graph of \(f(x) =\dfrac{1}{x2}+1\) it looks like dw:1438655236291:dw

Best ResponseYou've already chosen the best response.2for domain, you see that x goes from infinitive to + infinitive except x =2dw:1438655384625:dw

Best ResponseYou've already chosen the best response.2for range, look at yaxis.dw:1438655427018:dw the graph goes from infinitive to +infinitive along yaxis but never have y =1, right? hence range is \(\mathbb R/\{1\}\)
