(08.02 MC) The function f(x) = −x2 − 9x + 10 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?

(06.02 MC) The function f(x) represents the time it takes a commuter to travel in the morning to work. The function g(x) represents the time it takes a commuter to travel in the evening from work. Given f(x) = 5x − 7 and g(x) = 11x − 1, solve for (f + g)(x) to determine the total roundtrip time.

(5.01, 5.03, 5.06, 6.09, MC) Read the following speech excerpt and then select the correct answer to the question below: President George W. Bush’s speech to the troops on the USS Abraham LincolnOur mission continues. Al-Qaida is wounded, not destroyed. The scattered cells of the terrorist network still operate in many nations, and we know from daily intelligence that they continue to plot against free people.
