Answer:

  quadratic

Step-by-step explanation:

The x-values are sequential, so we can look at the y-values.

Differences from one to the next are ...

  -7, -1, 5, 11, 17

And the differences of these numbers are ...

  6, 6, 6, 6

When <em>second</em> differences are constant, the sequence can be produced by a <em>second</em>-degree (quadratic) polynomial.

__

Here, that polynomial is ...

  y = 3x² +2x -1

The regression functions of a graphing calculator can help you find the appropriate formula.
