Graphs A and B are the result of combining two linear functions, f(x) and g(x). The functions were combined by addition to form h(x), and then multiplication to form j(x).

Which statements describe the graphs? Select two options.
Graph B represents h(x).
Graph B represents j(x).
The y-intercepts of f(x) and g(x) can be -1 and 6.
The y-intercepts of f(x) and g(x) are both positive.
The rate of change for both f(x) and g(x) must be positive.
