Question 15 (1 point) Four exponential functions are given by the equations y = 2(3)*, y = 7(0.25)*, y = 0.5(7)*, y = (1/3)*. The curve that increases most sharply has a base of A/Question 14 (1 point) An antique painting has been appreciating at a rate of 11%/year since it was purchased in the year 1955. In the year 2000 the painting was worth $125000. The value of the painting, to the nearest dollar, that it was purchased for in the year 1955 was $ AQuestion 12 (1 point) The domain of the exponential function y = = (5)* is Oal {yly E R} Ob) {x x > 0, x E R) O c { yly > 0, y ER}Question 11 (1 point) A student saved $3500 from a summer job. The student invests this money in an investment at 12%/a compounded monthly. A function that models the growth of the investment is y = 3500(1. 01) , where y represents the value of the investment after x months. The number of months that it will take the investment to earn at least $600 in interest is A/Question 10 (1 point) There are initially 3000 bacteria in a culture. The bacteria will double every 5 hours. The number of bacteria, N, after t hours can be found using the formula N t) = 3000(2) . The number of hours, to the nearest hundredth, it will take the culture to grow to 75000 bacteria is A/ hours.Question 9 [1 point) The solution, to the nearest tenth, of the exponential equation 62341 : 5I+2 is CH Question 8 {1 point) I The following correct statement about an exponential equation, 3; : 3 (i) is O a) The graph is increasing from Quadrant II to Quadrant I because the base is greater than 1.
