Which type of function would best model the data below?
x | 5 | 7 | 8 | 11 | 13 | 14 | 17 | 19 | 20
f(x) | 2 | 6 | 7 | 4 | 2 | 2 | 3 | 5 | 9
The data does not follow a consistent pattern that fits a linear, quadratic, cubic, or exponential function perfectly. However, the values of f(x) seem to fluctuate without a clear linear or exponential trend, suggesting that a cubic function might be the best fit due to its ability to model more complex, non-linear relationships.
