a. z(–2) = –26; z(7) = 143
b. z(–2) = –10; z(7) = 143
c. z(–2) = 11; z(7) = 101
d. z(–2) = –2; z(7) = 241

Apolynomial function has a root of –6 with multiplicity 1, a root of –2 with multiplicity 3, a root of 0 with multiplicity 2, and a root of 4 with multiplicity 3. if the function has a positive leading coefficient and is of odd degree, which statement about the graph is true?
