1 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
