Answer:

Therefore, the potential roots of the function p(x) are ±6, ±1, and ±3. Options (1), (2), and (3) are true.

Explanation:

According to the Rational Root Theorem, the potential roots of a polynomial function are the rational numbers that can be obtained by dividing the factors of the constant term by the factors of the leading coefficient.

Let's analyze the provided options:

±6:

Constant term factors: ±1, ±2, ±3, ±4, ±6, ±12

Leading coefficient factor: ±1

Potential root: ±6 (dividing constant term factor by leading coefficient factor)

±1:

Constant term factors: ±1, ±2, ±3, ±4, ±6, ±12

Leading coefficient factor: ±1

Potential root: ±1 (dividing constant term factor by leading coefficient factor)

±3:

Constant term factors: ±1, ±2, ±3, ±4, ±6, ±12

Leading coefficient factor: ±1

Potential root: ±3 (dividing constant term factor by leading coefficient factor)

±8:

Not a factor of the constant term (12)

Not a potential root

Therefore, Options (1), (2), and (3) are true.
