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.

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