Best ResponseYou've already chosen the best response.0I graphed both and so far I wrote down These are both rational functions but the first one is up and the second is down. But I need to know how to get the domain and range. Thanks!

Best ResponseYou've already chosen the best response.1Wouldn't call them rational functions, but linear functions... Rational functions are e.g. f(x)=(x+2)/(x²3)

Best ResponseYou've already chosen the best response.0But the graphs look rational they're like the letter L

Best ResponseYou've already chosen the best response.1Here is how they look if I draw them: BTW, what does the letter "L" have to do with it?

Best ResponseYou've already chosen the best response.1To find the domain, you must ask yourself: what numbers can I use to put into these functions? ANd: are there any restrictions?
