Consider the three functions:

f(x) = Three-halves(4)x g(x) = Three-halves(4)–x h(x) = –Three-halves(4)x

Which statements are true about the domain and range of f(x), g(x), and h(x)? Check all that apply.

f(x) has a domain of all real numbers.
g(x) has a range of y < 0.
h(x) has a range of y > 0.
g(x) has a domain of all real numbers.
h(x) has a domain of x > 0.
