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?
polynomial
longarithmic
step
absolute value

1e+27

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
