The growth of a population of mountain lions can be described by the function f(x) = 500(1.015)x, where x is the number of years after the first census. How do the mathematical domain and range compare to the reasonable domain and range? Check all that apply.The mathematical and reasonable domains are identical.The mathematical domain is the set of real numbers, while the reasonable domain only includes real numbers greater than or equal to 0.The mathematical domain is the set of real numbers, while the reasonable domain cannot include fractional values.The mathematical range contains all real numbers, while the reasonable range contains all real numbers greater than 0.The mathematical range has a minimum value greater than 0, while the reasonable range is limited to whole numbers and has a minimum value greater than or equal to 500.
The amount of bacteria, f(x), observed by a research scientist is represented by the function f(x) = 3x + 7, where x is the number of hours passed since initial observation.Which statement best compares the mathematical and reasonable ranges for this function?
