Question 1(Multiple Choice Worth 1 points) (03.08 LC) A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce: f(n) = 9(0.7)n What does the number 9 in the function represent? Number of times the ball was dropped Height from which the ball was dropped Height to which the ball will bounce at the nth bounce Number of times the ball bounces at the nth bounce Question 2(Multiple Choice Worth 1 points) (03.01 LC) Simplify the square root of 2 times the cube root of 2. two to the one sixth power two to the two thirds power two to the five sixths power two to the seven sixths power Question 3(Multiple Choice Worth 1 points) (03.03 LC) Given the exponential function f(x) = 16(0.75)x, classify the function as exponential growth or decay and determine the percent rate of growth or decay. Exponential growth, 75% increase Exponential decay, 75% decrease Exponential growth, 25% increase Exponential decay, 25% decrease Question 4(Multiple Choice Worth 1 points) (03.08 MC) Two different businesses model their profits over 15 years, where x is the year, f(x) is the profits of a garden shop, and g(x) is the profits of a construction materials business. Use the data to determine which function is exponential, and use the table to justify your answer. x f(x) g(x) 1995 $14,170.20 $11,008.31 2000 $19,396.20 $16,174.82 2005 $24,622.20 $23,766.11 2006 $25,667.40 $25,667.40 2007 $26,712.60 $27,720.79 2010 $31,938.60 $34,920.21 g(x) is exponential; an exponential function increases faster than a linear function. g(x) is exponential; g(x) has a lower starting value and higher ending value. f(x) is exponential; an exponential function increases more slowly than a linear function. f(x) is exponential; f(x) increased less overall than g(x). Question 5(Multiple Choice Worth 1 points) (03.04 MC) The population f(x), in millions, of State A of a country after x years is represented by the function shown below: f(x) = 2(1.08)x The graph shows the population g(x), in millions, of State B of the country after x years: graph of exponential function g of x that curves up from left to right and goes through points 0 comma 2 and 9 comma 4 Which conclusion is correct about the populations of State A and State B? The original population of State B was half the original population of State A. The original population of State A was half the original population of State B. The ori
