The correct answer is Choice C.
Given that the relationship between time and the amount of the microbes is exponential, an increasing exponential function will be the best fit: $g(t) = g_0 X^t$, where $g_0$ is the initial amount of the microbes and $X$ is the growth factor. Find the two variables and substitute.
Choices A and D are incorrect because the initial number of microbes is not correct, and the growth factor in percentage should be expressed in decimal.
Choice B is incorrect because the initial number of microbes is not correct.
✨ Expert's Tip ✨
An alternate method is to substitute the tabulated values in each of the given functions to verify them.
