### 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

not enough information

### Best Answer

4. y = x^4 + 2x^3 – 3x^2 – 2x + 1

5. interpolation

6. Cubic

I just took the test and these were right :)
