Question: If the polynomial f(x) = x^4 - 4x^3 + 6x^2 - 4x + 1, what can be inferred about its symmetry?

Options:

Correct Answer: It is symmetric about the line x = 1.

Solution:

The polynomial can be rewritten in a form that shows symmetry about the line x = 1.

If the polynomial f(x) = x^4 - 4x^3 + 6x^2 - 4x + 1, what can be inferred about its symmetry?

Step 1: Identify the polynomial given: f(x) = x^4 - 4x^3 + 6x^2 - 4x + 1.
Step 2: Check if the polynomial can be expressed in a different form that reveals symmetry.
Step 3: Notice that the coefficients of the polynomial suggest it might be related to (x - 1)^4.
Step 4: Rewrite the polynomial as f(x) = (x - 1)^4, which expands to x^4 - 4x^3 + 6x^2 - 4x + 1.
Step 5: Recognize that (x - 1)^4 is symmetric about the line x = 1 because it is a perfect square.
