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.

anonymous · Answer

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

anonymous · Answer

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

welshfella · Answer

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

anonymous · Answer

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

welshfella · Answer

yes
