find the inverse of f(x)=x^3 +3 find the domain and range of f(x)

f(x)=x^3 +3
f%28x%29-3=x%5E3

f%28x%29-3=x%5E3

cuberoot%28f%28x%29-3%29=x

so the inverse is g(x):
%0D%0Ag%28x%29=cuberoot%28x-3%29%0D%0A

%0D%0Ag%28x%29=cuberoot%28x-3%29%0D%0A

The domain and range of both f and g are both all real numbers
