Question

Find the best indicated value of the function, which of the four options is it? Please explain why too btw please

Answer 1

$f(x)=\frac{-3x}{5}$

I can try replacing x=10 to know the real solution

$\begin{gathered} f(10)=\frac{-3(10)}{5} \\ f(10)=\frac{-30}{5} \\ f(10)=-6 \end{gathered}$

so, the solution is option 1
