## anonymous one year ago What is the domain of the following function? Will give medal. Just need help checking work!! (graph is included in attachment below!) I do not have a full understanding of this concept, but it seems that this domain is defined by infinity (the parabola goes on forever.) If this answer is indeed correct, I just do not know how to write it. Thanks!

the domain is all the possible values of x that can be applied to the function and in this case it is all real numbers.

3. anonymous

and that is just how I write it? that it is all real numbers?

4. anonymous

thank you! Would you mind helping me with one more question?

5. welshfella

Yes or in interval notation it is $(-\infty,+\infty)$

6. anonymous

$x \in \mathbb{R}$ or in this notation i think

7. welshfella

yes

8. welshfella

ok

9. anonymous

great! Thank you so much. Ok here is the other question one second

What is the domain of the following function? (just another domain question.)
