To find all possible rational zeros of the function \( f(x) = 6x^4 - 3x^2 + 2 \) using the Rational Zero Theorem, we need to examine the factors of the constant term and the leading coefficient.

  1. Identify the constant term and leading coefficient:

    • The constant term (the term without \( x \)) is \( 2 \).
    • The leading coefficient (the coefficient of the highest degree term \( x^4 \)) is \( 6 \).
  2. List the factors of the constant term \( 2 \):

    • The factors of \( 2 \) are \( \pm 1, \pm 2 \).
  3. List the factors of the leading coefficient \( 6 \):

    • The factors of \( 6 \) are \( \pm 1, \pm 2, \pm 3, \pm 6 \).
  4. Form possible rational zeros by taking all combinations of the factors of the constant term over the factors of the leading coefficient:

    • Possible rational zeros are:
      • \( \frac{\text{factor of constant}}{\text{factor of leading coefficient}} \)

    This leads to the following combinations:

    • \( \pm 1 = \frac{1}{1} \) and \( \frac{-1}{1} \)
    • \( \pm 2 = \frac{2}{1} \) and \( \frac{-2}{1} \)
    • \( \pm \frac{1}{2} = \frac{1}{2} \) and \( \frac{-1}{2} \)
    • \( \pm \frac{1}{3} = \frac{1}{3} \) and \( \frac{-1}{3} \)
    • \( \pm \frac{1}{6} = \frac{1}{6} \) and \( \frac{-1}{6} \)
    • \( \pm \frac{2}{3} = \frac{2}{3} \) and \( \frac{-2}{3} \)
    • \( \pm 3 = \frac{3}{1} \) and \( \frac{-3}{1} \)
    • \( \pm 6 = \frac{6}{1} \) and \( \frac{-6}{1} \)
  5. Combining all these, we have the list of possible rational zeros:

    • \( \pm 1, \pm 2, \pm \frac{1}{2}, \pm \frac{1}{3}, \pm \frac{1}{6}, \pm \frac{2}{3}, \pm 3, \pm 6 \)

Thus, the correct response from your options can be narrowed down to:

  • Response: \( \pm 1, \pm 2, \pm \frac{1}{2}, \pm \frac{1}{3}, \pm \frac{1}{6}, \pm \frac{2}{3} \)
