Answer:
A) -3
Step-by-step explanation:
Given the graph of f(x) and that g(x) = 2f(9 - (4/3)x) - 3, we can find g(9) by substituting x = 9 into the equation of g.
[tex]$\begin{align}g(9) &= 2f\left(5 - \frac43\times9\right)-3\\&=2f\left(5-12\right)-3\\&=2f(-7)-3\\&\texttt{According to the graph of }f(x)\text{, }f(-7)=0\\&=2\times0-3\\&=-3\end$[/tex]
Therefore, g(9) = -3.
