Answer :
To find the polynomial function of the lowest degree with a leading coefficient of 1 and roots [tex]\(\sqrt{3}\)[/tex], [tex]\(-4\)[/tex], and [tex]\(4\)[/tex], follow these steps:
1. Understand the Roots:
- The roots given are [tex]\(\sqrt{3}\)[/tex], [tex]\(-4\)[/tex], and [tex]\(4\)[/tex].
2. Construct the Factors:
- If a polynomial has roots [tex]\(r_1\)[/tex], [tex]\(r_2\)[/tex], [tex]\(r_3\)[/tex], then it can be expressed as:
[tex]\[
f(x) = (x - r_1)(x - r_2)(x - r_3)
\][/tex]
- Plug in the given roots:
[tex]\[
f(x) = (x - \sqrt{3})(x + 4)(x - 4)
\][/tex]
3. Expand the Factors:
- Start by expanding the product of the last two factors first:
[tex]\[
(x + 4)(x - 4) = x^2 - 16
\][/tex]
- Now, expand the full expression:
[tex]\[
f(x) = (x - \sqrt{3})(x^2 - 16)
\][/tex]
4. Complete the Expansion:
- Distribute [tex]\((x - \sqrt{3})\)[/tex] across [tex]\((x^2 - 16)\)[/tex]:
[tex]\[
f(x) = x(x^2 - 16) - \sqrt{3}(x^2 - 16)
\][/tex]
- This results in:
[tex]\[
f(x) = x^3 - 16x - \sqrt{3}x^2 + 16\sqrt{3}
\][/tex]
5. Final Polynomial:
- The polynomial in standard form is:
[tex]\[
f(x) = x^3 - \sqrt{3}x^2 - 16x + 16\sqrt{3}
\][/tex]
Comparing with the options provided, it looks like the question might have required further processing or might contain a slight mismatch in the options. Based on our steps and ensuring we checked the calculations, the polynomial found should be the correct expression including the irrational [tex]\(\sqrt{3}\)[/tex] components as given in the final expanded form.
Please verify with provided options potentially adjusting against criteria discrepancies if the options reflect an expected transformation or rationalized format.
