A lottery winner must choose between g(x) and h(x) for the distribution of winnings. Each month the distribution increases as shown in the tables. If the payout will last two years, which plan should the winner choose and why?

• The winner should choose g(x) because the table starts with thousands.

• The winner should choose h(x) because it will eventually yield more money.

• g(x) will eventually yield more money than h(x).

• The graph of f(x) always exceeds the graph of g(x) over the interval [0,5].

• The graph of g(x) always exceeds the graph of f(x) over the interval [0,5].

• The graph of g(x) exceeds the graph of f(x) over the interval [0,4], the graphs intersect at a point between 4 and 5, and then the graph of f(x) exceeds the graph of g(x).

• The graph of f(x) exceeds the graph of g(x) over the interval [0,4], the graphs intersect at a point between 4 and 5, and then the graph of g(x) exceeds the graph of f(x).
