Final answer:
The function h(x) = x^3 has an inverse relation that is also a function because the graph of h(x) passes the vertical line test.
Step-by-step explanation:
The correct statement that could be used to explain why the function h(x) = x^3 has an inverse relation that is also a function is option A) The graph of h(x) passes the vertical line test.
The vertical line test is a test used to determine if a graph represents a function. If every vertical line that intersects the graph crosses the graph at only one point, then the graph represents a function. In the case of the function h(x) = x^3, every vertical line intersects the graph at only one point, which means that the graph passes the vertical line test and therefore the inverse relation is also a function.
