35 point question, will mark brainliest. which of the following options is a 3rd degree polynomial with exactly 1 real root?

The correct option is D.

Step-by-step explanation:

In option A,

The given function is

Equate the function equal to zero, to find the roots.

The real root of this function is -3 with multiplicity 3. It means this function has 3 real roots.

In option B,

The given function is

Equate the function equal to zero, to find the roots.

Therefore, this function has 3 real roots.

In option C,

The given function is

Equate the function equal to zero, to find the roots.

The real root of this function is 3 with multiplicity 3. It means this function has 3 real roots.

In option D,

Equate the function equal to zero, to find the roots.

The roots of this functions are -3, 3i and -3i. Since this function has exactly one real root, therefore option D is correct.
