Answer 1

What's your question? haha

Answer 2

determine the domain \[f(x)=\sqrt{9-x ^{2}}\]

Answer 3

Do you know what the question is asking for? i.e. do you know what the domain of a function is?

Answer 4

the question just says determine the domain of \[f(x)=\sqrt{9-x ^{2}}\]

Answer 5

Yes I know. But do YOU know what it means? What is the "domain"

Answer 6

oh lol isnt it a set of functions with all possible inputs from neg to pos or infinite?

Answer 7

wouldn't i be breaking down the square root of 9 - x squared (3-x)(3+x)

Answer 8

It is all the values of x that you could put into your function to get an output value.

So a better question would be to ask yourself what values of x can I put into the function that makes it DNE

Answer 9

what does DNE mean?
