Algebra 2 help please?


What polynomial has a graph that passes through the given points?

(–4, 89), (–3, 7), (–1, –1), (1, –1), (4, 329)


y = 2x^3 – 3x^2 – 2x + 1
y = 1x^4 – 2x^3 – 3x^2 + 2x + 1
y = x^4 – 2x^3 + 3x^2 + 2x – 1
y = x^4 + 2x^3 – 3x^2 – 2x + 1

5.Would the prediction be considered interpolation or extrapolation?

interpolation
extrapolation

6.Suppose a data set follows the path of a polynomial with two turning points. Which type of polynomial function is most likely to best fit the data set?

linear
quadratic
cubic
