Question

I just need the graph done, I have no idea how to do it :(

Answer 1

Part 1 -
f(x) = 2x - 4
g(x) =
x + 4 / 2

Part 2 -
f(x) = 2x - 4
Change f(x) for y
y = 2x -4
Switch x and y
x = 2y -4
Isolate y by adding 4 to both sides
x + 4 = 2y
Divide both sides by 2
x + 4 = 2y / 2
y = x + 4 / 2

Part 3 -
g(f(x)) = (2x - 4) +4 / 2

and part 4 is the graph.. But that is the work you need in order to complete the graph.
