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
