Construct a polynomial function of least degree possible using the given information. real roots: −1, 1, 3 and (2, f(2)) = (2, 5)

f(x) = (-5/3)x³ +5x² +(5/3)x -5

Step-by-step explanation:

For root "a", the polynomial will have a factor (x -a). Given the three roots, the polynomial will be the product of the three factors ...

... p(x) = (x +1)(x -1)(x -3)

The value of p(2) is 3·1·(-1) = -3. In order to make f(2) = 5, we need to multiply p(x) by -5/3.

... f(x) = (-5/3)p(x)

... f(x) = (-5/3)(x +1)(x -1)(x -3)

Expanding gives

... f(x) = (-5/3)x³ +5x² +(5/3)x -5

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
