Question

Which statement best compares the domain and range of , g(x) = x3, and h(x) = x?

The domain and range of all three functions are all reals.
The domain and range of g(x) and h(x) are all reals. The domain and range of f(x) do not include 0.
The domain and range of f(x) and h(x) are all reals. The domain and range of g(x) do not include 0.
The domain of all three functions is all reals. The range of f(x) and h(x) is all reals, while the range of g(x) contains all reals greater than or equal to 0.

Answer 1

Answer: b

Step-by-step explanation: looking at the graph, we can see that g(x) and h(x) has domain of all real number.And the domain and range of f(x) do not include 0.
