##### 1 Answer

#### Answer:

The equation has

#### Explanation:

First we write the polynomial in standard form:

Since the polynomial is of degree three, the fundamental theorem of algebra tells us that it has

I presume the question is asking for the number of real roots, so to determine whether the function has

If you have a cubic equation in the form

If

In our case, we get
