Question

Polynomial problem is: degree 3 polynomial that goes through (5, -12.6) find the polynomial. Any ideas?

Answer 1

There are only so many possible answers to this :D

Answer 2

Did that an the answer I got the math system says is wrong. My answer was: f(x) = x^3(x+2)^2(x-2)

Answer 3

Thing is, when you let x = 5, f(x) has to be equal to -12.6

Answer 4

f(x)=ax^3
-12.6=a(5)^3
a=-.1008
f(x=-.1008x^3

Answer 5

\[\large f(x)=-0.1x^3-0.1=-\frac{x^3+1}{10}\]

Answer 6

According to WEBwork that is not the correct answer.

Answer 7

It is probably a simple matter of the form. What do the directions say about entering answers?

Answer 8

The = sign cannot be used as it is an unacceptable character

Answer 9

No other directions? How does it say to enter fractions?

Answer 10

use the division sign for fractions /
