At the time an antibiotic is applied to a population of bacteria, the population is growing as defined by the function p(x) = 300(1.05)x, where x represents time, in hours. At the same time, the antibiotic reduces the population by 30% each hour. The effect of the antibiotic can be represented by the function a(p) = p(0.7)x. Which function represents a(p(x))? a(p(x)) = 300(0.735)^x a(p(x)) = 220.5^x a(p(x)) = 300(1.035)^x a(p(x)) = 310.5^x
