Consider the functions f(x)=3x^2, g(x)=1/3x, and h(x)=3x. Which statements accurately compare the domain and range of the functions? Select two options. 1. All functions have a unique range.
2. The range of all three functions is all real numbers.
3. The domain of all three functions is all real numbers.
4. The range of f(x) and h(x) is all real numbers, but the range of g(x) is all real numbers except 0.
5. The domain of f(x) and h(x) is all real numbers, but the domain of g(x) is all real numbers except 0.
