+223 Please do your best to explain since I want to learn how to do this as well.
+180 (b):
Take a point (a,b) on the graph of y=f(x), so b=f(a). Since \(\left( 3a - 1, \frac{b}{2} \right)\) lies on the graph of y=g(x) we have that \(\frac{b}{2} = g(3a - 1). \)
Substituting b=f(a) we get \(\frac{f(a)}{2} = g(3a - 1).\)
In order to express g(x) in terms of f(x) we can let x = 3a-1 Then a=\(\frac{x + 1}{3}\), so
\(g(x) = \frac{f(a)}{2} = \frac{1}{2} f \left( \frac{x + 1}{3} \right).\)
+180 Sorry that I can't do the problems (a) and (c) because the LaTeX code is too complicated for drawing the diagram. I hope you understand
+223 It's okay, I understand, can anyone else help? It's due tomorrow for me.

+223 Yeah... I looked at that one, I wasn't able to understand what they are saying though, thanks for the help!
+180 First, we observe that the graph of y=f(x) consists of line segments, connecting the points (-4, 4), (-1,0), (0,2), and (4,-4).
So to plot the graph of y=g(x) we can apply the transformation \((a,b) \to \left( 3a - 1, \frac{b}{2} \right)\) to each of these points, and then connect them. This gives us the points (-13,2), (-4,0), (-1,1), and (11,-2).
Hope this helps!
I got it working.
