A quick question about Composite functions

Hi everyone

Just checking if the domain of f(g(x) is equal to the domain of g(x), then the range of f(g(x) is equal to what?

Thanks

Range of f(g(x)) is equal to f(g(x))'s end function's range.

The range of g(x) must be a subset of the domain of f(x) (domain of f(x) must include the range of g(x))
Input the range of g(x) into f(x) and that's your range
