Step-by-step explanation: Minumum as in of the graphed thing and the minimum/maximum of it or the answer to y or x because that’s impossible
The fundamental theorem of algebra states that a polynomial of degree has exactly n roots (including complex and multiple).
The degree of a polynomial is the highest (non-negative) exponent of the polynomial, in this case is 17 from the term 15x^17.
None of them match the answer is really (-2,2), (-4,2), and (-2,8).
