Question

Which polynomial function best represents the four ordered pairs given in the example? Reminder : The ordered pairs are (1, 6); (2, 11); (4, 39); and (7, -54).

Answer 1

f(x) = -2x³ +17x² -32x +23

Explanation:

It is usually sufficient to try the values of a couple of points in the offered answer selections to see which one fits.

You have not provided any choices, so I have used the polynomial regression function of a graphing calculator to compute the cubic that will represent these ordered pairs exactly.
