(08.06 LC) A company launches two new products. The market price, in dollars, of the two products after a different number of years, x, is shown in the following table: Product Function Year 1(dollars) Year 2(dollars) Year 3(dollars) Product 1 g(x) = x2 + 11 12 15 20 Product 2 h(x) = 4x 4 16 64 Based on the data in the table, for which product does the price eventually exceed all others, and why?

(08.02 MC) The function f(x) = −x2 − 7x + 30 shows the relationship between the vertical distance of a diver from a pool’s surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. What is a zero of f(x), and what does it represent?
