A car travels at a rate of 50 miles per hour for 4 hours let Y be the distance in miles in the car travels for a given amount of time in X hours this situation can be modelled by a function which of these describes the domain of the function

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
