Question

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? The mathematical and reasonable ranges are all real numbers. Both the mathematical and reasonable ranges have an unknown upper limit. The mathematical range is all real numbers greater than 7. The reasonable range is whole numbers greater than or equal to 8, with an unknown upper limit. The mathematical range is all real numbers greater than 0. The reasonable range is all whole numbers. Both the mathematical and reasonable ranges have an unknown upper limit. The mathematical range is all real numbers greater than or equal to 7. The reasonable range is whole numbers greater than 8, with an unknown upper limit.
