Stuck! Please help!
"What is the domain and range of the rainbow (parabola f(x) x^2 + 36) Explain what the domain and range represent. Do all of the values make sense in this situation? Why or why not?"
I'm not completely sure what they're asking for? I'm sure the answer is really simple but these questions are very vague to me...

Best ResponseYou've already chosen the best response.0is your parabola x^2+36 or (x^2+36) x^236?!!!

Best ResponseYou've already chosen the best response.0I understand what domain and range is, I'm just not completely sure about what they're asking for when they say what do the domain and range represent in the rainbow and if all the values make sense in the situation

Best ResponseYou've already chosen the best response.0f(x) = x^2 + 36 that is what you meanc ?

Best ResponseYou've already chosen the best response.0We say "the domain is x" what this means is that the domain is any number that you can plug in for x (without getting undefined output) is the domain.

Best ResponseYou've already chosen the best response.0We say "the range is y" this means that range is any value of y that you can possibly get in a function.

Best ResponseYou've already chosen the best response.0For example, your case: you have \(\large f(x)=x^236\) is there a number that you can't plug for x because are going to get an undefined output, or there is no such a number?

Best ResponseYou've already chosen the best response.0oh, \(f(x)=x^2+26\) but for domain that doesn't matter

Best ResponseYou've already chosen the best response.0I know. The only part I'm really stuck on is if all the values make sense in the situation

Best ResponseYou've already chosen the best response.0The domain of f(x) is (∞, ∞), but all values of x don't make sense for the application. For example, if you were to consider the xaxis as the ground (or whatever surface the rainbow starts and ends on), then the domain for this application is [6, 6]. Similarly the range of f(x) is (∞, 36), but only [0, 36] make sense.

Best ResponseYou've already chosen the best response.0what is the range and domain if you dont mind me asking

Best ResponseYou've already chosen the best response.0@kimberlylopez the domain is usually on the xaxis (left to right) and the range is usually on the yaxis (down to up). I agree with @peachpi that the domain is indeed from 6 to 6 ... [6,6]... the range is negative infinity to 36 but only 0 to 36 makes sense..
