James is researching earthquakes for a science report. He is trying to come up with his own
scale to rank the intensity of an earthquake.
He notices that the difference in the intensity
of the smallest earthquake, x, and the largest
earthquake, y, is a magnitude of several
hundred thousand. James comes up with a
scale that allows him to show these
differences and is easy to use and interpret.
Which of the following functions would best model the situation above?
A. step
B. logarithmic
C. absolute value
D. polynomial

the answer is B) logarithmic

Step-by-step explanation:

In the given situation, James wants to find a way to distinguish between a very small intensity, x, and a very large intensity, y. To plot this with most graphs, it would involve using an axis that has a magnitude range of several hundred thousand. However, a logarithmic function allows for a single digit change to represent an increase in magnitude by a factor of ten.

Therefore, the situation is best modeled by a logarithmic function.
