Question

Find a polynomial function to model the data.
A.



f(x) = –0.68x3 + 6.96x2 – 19.91x + 2


B.



f(x) = 0.68x3 – 6.96x2 + 19.91x – 2


C.



f(x) = 0.68x2 – 6.96x – 2


D.



f(x) = 0.068x3 – 6.96x2 + 19.91x – 2

Answer 1

Use a calculator and substitute the values of x in the table/data into the equations and determine whether the equation would give you the corresponding y-value in your data table.

Answer 2

f(x) value.

Answer 3

what numbers do i plug in

Answer 4

c=d
a is not correct because of -.68x^3 (for large positive x f(x)<0)

Answer 5

so what would the answer be?

Answer 6

c or d they equal
