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?
Answer
A
The mathematical and reasonable ranges are all real numbers. Both the mathematical and reasonable ranges have an unknown upper limit.
B
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.
C
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.
D
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.
