how to find the domain in g(x)=x^3+2

Question

anonymous · Answer

all real numbers since you have a polynomial

anonymous · Answer

you can cube any number, and add two to any number, so there is no number for which this function would not return a real answer

.sam. · Answer

$$\mathbb{R}$$ (all real numbers)
(assuming a function from reals to reals)

anonymous · Answer

can u show me the solution

anonymous · Answer

now that we know what your teacher wants, i would like to add that the question actually makes no sense
the "domain" is supposed to be part of the definition of a function, and the question "find the domain" is meaningless 
but your teacher wants "all real numbers"

anonymous · Answer

there is no "solution" in terms of algebra
the question is "what it the domain" and the answer is "all real numbers" 
there is no work to show
