Question

An exponential function that is used to measure the amount of bacteria spores (s) present in a public restroom over a certain number of days (d).A. d > 0, where d is a real numberB. s < 0, where s is a negative, real number C. d < 0, where d is a negative, real number D. s > 0, where is a real number

Answer 1

Answer: D. s > 0, where s is a real number.

Step by step solution:

The exponential function that measures the amount of bacteria spores over a certain number of days is:

`s=s^d_0`

s and d can not be negative, because the number of bacterias or days will not take negative values, the number of bacterias will increase as the days increase. s represents the function, and d is the exponent.
