What I think : \[g(x)=2f(\frac{ 1 }{ 2 }x) +3\] If you evaluate for x=4, \[g(4)=2f(2)+3\] by looking at the graph, you see that f(2) = 0 thus, \[g(4)=3\]

I'm not sure what they mean by "use transformations"

they mean like apply all the changes to the graph looking at the formula above like the () means it's reflect on the x axis, but i dont understand the rest

You'd have to draw a second graph of \[y_{g}=g(x)\], using the formula and the graph \[y_{f}=(\frac{ 1 }{ 2 }x)\]

\[y _{g}=2y _{f}+3\] \[y _{f}\] is found by looking at the first graph, at a value on the xaxis that is x/2
