Question

7 of 1010 PointsThat is the multiplicity of each of the roots of the graph of f(x) = 2x + 12r³ +16r² - 12x - 18?-3, multiplicity 1; -1, multiplicity 1; 1, multiplicity 1B.-3, multiplicity 2; -1, multiplicity 3; 1, multiplicity 1C.-3, multiplicity 2; 1, multiplicity 2D.-3, multiplicity 2; -1, multiplicity 1; 1, multiplicity 1set Selection

Answer 1

Solution:

Given the function;

$f(x)=2x^4+12x^3+16x^2-12x-18$

The graph of the function is;

Thus, the multiplicity of each of the roots of the graph is;

$\begin{gathered} -3,multiplicity\text{ }2; \\ \\ -1,multiplicity\text{ }1; \\ \\ 1,multiplicity\text{ }1 \end{gathered}$
