Since the function's degree is

#### Explanation:

The Fundamental Theorem of Algebra (FTOA), for a polynomial function such as

The degree of a function is the highest exponent on any of its terms, which in this case is the

Since this function has degree

graph{x^3-3x^2-18x-176 [-10, 15, -300, 70]}

Graphing the function, it appears to have only one root (zero) at *complex* roots for a total of
