helpful video,but 1 more question,when do we need to write "x e R"-[x includes all real numbers] in the answer when we are asked to find the domain?

[patrickJMT]

@chloetan2912 you are using set notation, i think i use interval notation. it is all the same thing, perhaps just ask your teacher if they have a preferred notation for you to use.

[Aupey]

Is there really a difference in finding the domain of this, a 2D function from a 3D function? Any help (even a yes or no) would be helpful!

[laglagga]

I feel so secure in my manhood, to say that you taught me to love math.
