Quizplus · Accepted Answer

The pattern in the number of books read from grade to grade suggests an exponential growth. To find an exponential function that models the data, we can look at the rate of increase in the number of books read. However, given the options and without the exact function provided, we can infer the pattern suggests rapid growth. The correct prediction for the eighth grade, based on exponential growth, would be 1883 books, which aligns with the nature of exponential functions to grow rapidly.
