Question

The graph is that of a fourth -degree polynomial function. which shows all of the factors of the function?

Answer 1

from the figure, we can see that the Real roots of the polynomial are

`\begin{gathered} x=-3 \\ x=2\text{ of degre}e\text{ 2 } \\ \text{and } \\ x=5 \end{gathered}`

hence, the polynomials factors are

`(x+3)(x-2)^2(x-5)`
