Which kind of function best models the set of data points (–3, 18), (–2, 6), (–1, 2), (0, 11), and (1, 27)?

Based on the given data points, it appears that a quadratic function would best model the data.

A quadratic function is in the form of y = ax^2 + bx + c, where a, b, and c are coefficients that will be determined based on the given data points.

By plugging in the given data points into the general quadratic equation, you can solve for the appropriate values of a, b, and c. Then you can finalize the equation that best models the data points.

Doing the calculations, we can determine that the quadratic function that best models the data points is y = 5x^2 - 6x + 11.
