Hence, the function is not differentiable at x=9
Using the rational root theorem, it is found that your friend is correct.
<h3>What is the rational root theorem?</h3>- It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format
.
In this problem:
- The leading coefficient is 1, hence it's only factor is
, thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.
