Answer 6

okay, so i choose 3.13 and 6.4

Answer 7

\( \begin{array}{llll}
x = 3.13\implies x-3.13=0\implies &(x-3.13)=0\\ \quad \\
x=6.4\implies x-6.4=0\implies &(x-6.4)=0
\end{array}\\ \quad \\\bf
\textit{that means that to get your function, multiply both roots}\\ \quad \\
(x-3.13)(x-6.4)=0\implies (x-3.13)(x-6.4)=y\)

Answer 8

thanks
