1) If we consider that y=f(2x) is a transformed version of y=f(x) then we can set a t-table and plug for the given point (16,8) the x-coordinate x=16


\begin{gathered} (16,8)-\longrightarrow f(x)-->y=(1)/(2)x \\ \end{gathered}

Since the new function, f(2x) requires us to divide the input by 2 to compensate
