Question

Let p(x) be a cubic polynomial with p(1)<0, p(6)>0, and p(8)<0. What can you say about the number and location of zeros of p(x)?

**answer choices attached inside :)

Answer 1

A,B,C,D,E from top to bottom :)

**A is definitely not an answer right? since there is a zero between x=1 and x=6, and x=6 and x=8 ?

but i'm not sure how to narrow down the last four choices based off the second part of the answers :/
