The population of an endangered mammal is decreasing at a ra

The population of an endangered mammal is decreasing at a rate of 0.45% per year There are currently about 150,000 of these mammals Select the most appropriate domain for the equation that models the amount of remaining mammal population. {x|x element R} {x|x greaterthanorequalto 0} {x|0 lessthanorequalto x lessthanorequalto 675} {x|0 lessthanorequalto x lessthanorequalto 150,000}

Solution

There are 150000 mammals presently. Further, the number of mammals cannot go down below 0 so that option D i.e. { x : 0 x 150000} represents the domain for the equation modelling the remaining mammal population.
